                    131: Fig. "XML for Map in Figure" shows the XML representation of the
                    132: resource map shown in Fig. "Example of a Map in the Advanced Editor",
                    133: which is the format in which maps are stored. In the figure, however,
                    134: additional graphical map layout information generated by the Advanced
                    135: Resource Assembly Tool is not displayed. This graphical information is
                    136: optional to re-generate the same graphical layout when the map is
                    137: brought up again in the Resource Assembly Tool, and is not needed for
                    138: any other system functionality.
                    139: 
                    140: Maps can be generated by tools other than the Resource Assembly
                    141: Tool. In particular, an author might have some other representation of
                    142: a course sequence, which can be converted into a map using scripts. If
                    143: this map then were to be brought up in the Resource Assembly Tool, the
                    144: Tool would automatically generate a graphical layout for it. Each
                    145: entry of the map (resources, conditions and links) is stored in a
                    146: separate tag.
                    147: 
                    148: Resources and conditionsX<conditions> have to have unique ID
                    149: numbers. These numbers are automatically generated by the Resource
                    150: Assembly Tool when the entry is first created, or added to the entries
                    151: when a map generated outside the Resource Assembly Tool is first
                    152: retrieved. They can also be assigned by custom scripts or added in by
                    153: hand.
                    154: 
                    155: In the XML example, entry 1 is the start resource of the map. When
                    156: this map is accessed, the source (src) URL of this tag will be the
                    157: first resource rendered. Entry 2 is the finish resource of this
                    158: map. This resource will be the last resource in the sequence of
                    159: resources. Entry 6 is a problem resource with the given URL and title,
                    160: as well as the priority "mandatory". Entry 19 is a condition, which is
                    161: used by the link between entries 6, the problem, and 9, a
                    162: sequence. I<The final syntax for conditions has not yet been
                    163: determined.>
