core attributes common to most HTML elements
</xs:documentation>
</xs:annotation>
<xs:attribute name="id" type="xs:ID">
<xs:annotation>
<xs:documentation>
This attribute defines a unique identifier (ID) which must be unique in the whole document. Its purpose is to identify the element when linking (using a fragment identifier), scripting, or styling (with CSS).
Usage note:
- This attribute's value is an opaque string: this means that web author must not use it to convey any information. Particular meaning, for example semantic meaning, must not be derived from the string.
- This attribute's value must not contain white spaces. Browsers treat non-conforming IDs that contains white spaces as if the white space is part of the ID. In contrast to the class attribute, which allows space-separated values, elements can only have one single ID defined through the id attribute. Note that an element may have several IDs, but the others should be set by another means, such as via a script interfacing with the DOM interface of the element.
- Using characters except ASCII letters and digits, '_', '-' and '.' may cause compatibility problems, as they weren't allowed in HTML 4. Though this restriction has been lifted in HTML 5, an ID should start with a letter for compatibility.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="class" type="xs:NMTOKENS">
<xs:annotation>
<xs:documentation>
This attribute is a space-separated list of the classes of the element. Classes allows CSS and Javascript to select and access specific elements via the class selectors or functions like the DOM method document.getElementsByClassName.
Usage note: Though the specification doesn't put requirements on the name of classes, web developers are encouraged to use names that describe the semantic purpose of the element, rather to the presentation of the element (e.g., attribute to describe an attribute rather than italics, although an element of this class may be presented by italics). Semantic names remain logical even if the presentation of the page changes.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="style" type="xs:string">
<xs:annotation>
<xs:documentation>
This attribute contains CSS styling declarations to be applied to the element. Note that it is recommended for styles to be defined in a separate file or files. This attribute and the <style> element have mainly the purpose of allowing for quick styling, for example for testing purposes.
Usage note: This attribute must not be used to convey semantic information. Even if all styling is removed, a page should remain semantically correct. Typically it shouldn't be used to hide irrelevant information; this should be done using the hidden attribute.

The HTML Meta Element (<meta>) represents any metadata information that cannot be represented by one of the other HTML meta-related elements (<base>, <link>, <script>, <style> or <title>).
Depending on the attributes set, the kind of metadata can be one of the following:
- If name is set, it is document-level metadata, applying to the whole page.
- If http-equiv is set, it is a pragma directive, i.e. information normally given by the web server about how the - web page should be served.
- If charset is set, it is a charset declaration, i.e. the charset used for the serialized form of the webpage. HTML5
- if the itemprop is set, a user-defined metadata, transparent for the user-agent as the semantics of the metadata is user-specific.

<xs:attribute name="scheme">
<xs:annotation>
<xs:documentation>
This attribute defines the scheme in which the metadata is described. A scheme is a context leading to the correct interpretations of the content value, like a format.
Notes: Do not use this attribute as it is obsolete. There is no replacement for it as there was no real usage for it. Omit it altogether.
</xs:documentation>
</xs:annotation>
</xs:attribute>
</xs:complexType>
</xs:element>
<xs:element name="link">
<xs:annotation>
<xs:documentation>
The HTML Link Element (<link>) specifies relationships between the current document and external resource. Possible uses for this element include defining a relational framework for navigation. This Element is most used to link to style sheets.
</xs:documentation>
</xs:annotation>
<xs:complexType>
<xs:attribute name="charset" type="xs:string">
<xs:annotation>
<xs:documentation>
This attribute defines the character encoding of the linked resource. The value is a space- and/or comma-delimited list of character sets as defined in RFC 2045. The default value is ISO-8859-1.
Usage note: This attribute is obsolete in HTML5 and must not be used by authors. To achieve its effect, use the Content-Type: HTTP header on the linked resource.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="href" type="xs:anyURI">
<xs:annotation>
<xs:documentation>
This attribute specifies the URL of the linked resource. A URL might be absolute or relative.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="hreflang" type="xs:language">
<xs:annotation>
<xs:documentation>
This attribute indicates the language of the linked resource. It is purely advisory. Allowed values are determined by BCP47 for HTML5 and by RFC1766 for HTML 4. Use this attribute only if the href attribute is present.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="type" type="xs:string">
<xs:annotation>
<xs:documentation>
This attribute is used to define the type of the content linked to. The value of the attribute should be a MIME type such as text/html, text/css, and so on. The common use of this attribute is to define the type of style sheet linked and the most common current value is text/css, which indicates a Cascading Style Sheet format.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="rel" type="xs:NMTOKENS">
<xs:annotation>
<xs:documentation>
This attribute names a relationship of the linked document to the current document. The attribute must be a space-separated list of the link types values. The most common use of this attribute is to specify a link to an external style sheet: the rel attribute is set to stylesheet, and the href attribute is set to the URL of an external style sheet to format the page. WebTV also supports the use of the value next for rel to preload the next page in a document series.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="rev" type="xs:NMTOKENS">
<xs:annotation>
<xs:documentation>
The value of this attribute shows the relationship of the current document to the linked document, as defined by the href attribute. The attribute thus defines the reverse relationship compared to the value of the rel attribute. Link types values for the attribute are similar to the possible values for rel.
Usage note: This attribute is obsolete in HTML5. Do not use it. To achieve its effect, use the rel attribute with the opposite link types values, e.g. made should be replaced by author. Also this attribute doesn't mean revision and must not be used with a version number, which is unfortunately the case on numerous sites.
</xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="media" type="MediaDesc">
<xs:annotation>
<xs:documentation>
This attribute specifies the media which the linked resource applies to. Its value must be a media query. This attribute is mainly useful when linking to external stylesheets by allowing the user agent to pick the best adapted one for the device it runs on.
Usage note:
- In HTML 4, this can only be a simple white-space-separated list of media description literals, i.e., media types and groups, where defined and allowed as values for this attribute, such as print, screen, aural, braille. HTML5 extended this to any kind of media queries, which are a superset of the allowed values of HTML 4.
- Browsers not supporting the CSS3 Media Queries won't necessarily recognize the adequate link; do not forget to set fallback links, the restricted set of media queries defined in HTML 4.

<xs:attribute name="defer">
<xs:annotation>
<xs:documentation>
This Boolean attribute is set to indicate to a browser that the script is meant to be executed after the document has been parsed. Since this feature hasn't yet been implemented by all other major browsers, authors should not assume that the script’s execution will actually be deferred. The defer attribute shouldn't be used on scripts that don't have the src attribute. Since Gecko 1.9.2, the defer attribute is ignored on scripts that don't have the src attribute. However, in Gecko 1.9.1 even inline scripts are deferred if the defer attribute is set.

The HTML <div> element (or HTML Document Division Element) is the generic container for flow content, which does not inherently represent anything. It can be used to group elements for styling purposes (using the class or id attributes), or because they share attribute values, such as lang. It should be used only when no other semantic element (such as <article> or <nav>) is appropriate.

The HTML unordered list element (<ul>) represents an unordered list of items, namely a collection of items that do not have a numerical ordering, and their order in the list is meaningless. Typically, unordered-list items are displayed with a bullet, which can be of several forms, like a dot, a circle or a squared. The bullet style is not defined in the HTML description of the page, but in its associated CSS, using the list-style-type property.
There is no limitation to the depth and imbrication of lists defined with the <ol> and <ul> elements.

This was the single required attribute for anchors defining a hypertext source link, but is no longer required in HTML5. Omitting this attribute creates a placeholder link. The href attribute indicates the link target, either a URL or a URL fragment. A URL fragment is a name preceded by a hash mark (#), which specifies an internal target location (an ID) within the current document. URLs are not restricted to Web (HTTP)-based documents. URLs might use any protocol supported by the browser. For example, file, ftp, and mailto work in most user agents.

This attribute specifies where to display the linked resource. In HTML4, this is the name of, or a keyword for, a frame. In HTML5, it is a name of, or keyword for, a browsing context (for example, tab, window, or inline frame). The following keywords have special meanings:
* _self: Load the response into the same HTML4 frame (or HTML5 browsing context) as the current one. This value is the default if the attribute is not specified.
* _blank: Load the response into a new unnamed HTML4 window or HTML5 browsing context.
* _parent: Load the response into the HTML4 frameset parent of the current frame or HTML5 parent browsing context of the current one. If there is no parent, this option behaves the same way as _self.
* _top: In HTML4: Load the response into the full, original window, canceling all other frames. In HTML5: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.
