   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.>
