+
+Fig. "XML for Map in Figure" shows the XML representation of the
+resource map shown in Fig. "Example of a Map in the Advanced Editor",
+which is the format in which maps are stored. In the figure, however,
+additional graphical map layout information generated by the Advanced
+Resource Assembly Tool is not displayed. This graphical information is
+optional to re-generate the same graphical layout when the map is
+brought up again in the Resource Assembly Tool, and is not needed for
+any other system functionality.
+
+Maps can be generated by tools other than the Resource Assembly
+Tool. In particular, an author might have some other representation of
+a course sequence, which can be converted into a map using scripts. If
+this map then were to be brought up in the Resource Assembly Tool, the
+Tool would automatically generate a graphical layout for it. Each
+entry of the map (resources, conditions and links) is stored in a
+separate tag.
+
+Resources and conditionsX<conditions> have to have unique ID
+numbers. These numbers are automatically generated by the Resource
+Assembly Tool when the entry is first created, or added to the entries
+when a map generated outside the Resource Assembly Tool is first
+retrieved. They can also be assigned by custom scripts or added in by
+hand.
+
+In the XML example, entry 1 is the start resource of the map. When
+this map is accessed, the source (src) URL of this tag will be the
+first resource rendered. Entry 2 is the finish resource of this
+map. This resource will be the last resource in the sequence of
+resources. Entry 6 is a problem resource with the given URL and title,
+as well as the priority "mandatory". Entry 19 is a condition, which is
+used by the link between entries 6, the problem, and 9, a
+sequence. I<The final syntax for conditions has not yet been
+determined.>
