         <li>
    <b>&lt;labelgroup&gt;</b> 1 required, multiple

    associated with them.  <br />Arguments:
    <ul>
     <li>
       <i>name</i> this is the name of the group, a hash
       with this name will be generated holding the
       mappings for later use in the problem. For each
       location a value will be set for which label is
       there, (EX. $hash{'1'}="TEXT-2"). For locations
       with values the hash will contain 2 items, a
       location to value mapping ($hash{'value_1'}=10),
       and a label to value mapping
       ($hash{'labelvalue_2'}=10). For all image style of
       labels there will also be a label description to
       label URL mapping ($hash{'image_2'}=IMG-URL). Also
       the entry 'numlocations will be set to the total
       number of locations that exist.
       (Note that locations and labels start counting from 1.)

       <h2> Form internals </h2>
       <p> Form elements used for homework editing/response </p>
       <p> the form is named lonhomework </p>
       <h3> Viewing a problem (either CSTR or RES space)</h3>
       <ul>
         <li>
    grade_target, grade_username, grade_domain, grade_symb - the
    vaules take precedence over the the normal ENV settings of
    these, use &Apache::lonxml::whichuser() to get back the
    correct vaues of the items
         </li>
         <li>
    HWVAL_response:number - the name of the input elements for each response. The response is the response's ID, and the :number part exists only for response with multiple foils, and is a unique number in order of the submission
         </li>
         <li>
    changerandseed - the 'Change' button, only exists right after
    the Change button is clicked
         </li>
         <li>
    problemmode - in CSTR, it is either 'View','Edit','EditXML' or
    'Analyze' depending on the desired view
         </li>
         <li>
    rndseed - the currently requested random seed
         </li>
         <li>
    showallfoils - if it exists, and we are in CSTR space, the
    problem should ignore &lt;conceptgroup&gt; and the response's
    max setting and show all possible foils
         </li>
         <li>
    submit - the name of the Submit button
         </li>
         <li>
    submitted - a hidden form parameter that can be used to tell
    if the student has submitted answers or not, if it is set,
    there should be answers to grade.
         </li>
       </ul>
       <h3> Editing a problem (Edit mode)</h3>
       <p> tagdepth referes to the current value of the xmlparsers tagdepth couter ($Apache::lonxml::currentdepth)</p>
   <p> Note: the file edit.pm has many helper functions for creating the standard elements for editing a tag and it's attributes, all of those functions follow these conventions </p>
       <ul>
         <li>
    tagdepth_argname - I.E. 1_3.max, a parameter editing value,
    max is the name of the parameter and it is for the third tag
    inside the first tag
         </li>
         <li>
    delete_tagdepth - if set to yes, delete tag tagdepth and all
    tags inside of it
         </li>
         <li>
    homework_edit_tagdepth - used by both &Apache::edit::editline
    and &Apache::edit::editfield for the &lt;textarea&gt; and
    &lt;input&gt; form elements they create
         </li>
         <li>
    insert_tagdepth - used to request an tag insert, it is set to
    the id number of the requested tag in the
    %Apache::lonxml::insertlist
       </ul>
