21.4.6.5 chPref (Preferred Number of Children)

This variable indicates the number of children that the current node prefers to have. This determines what the next action of the ‘Add Shape’ button should be in the user interface.

[Example: Consider the following example of chPref being used in DiagramML:

<varLst>                       
<chMax val="3" />          
<chPref val="1" />         
<dir val="norm" />         
<animLvl val="lvl" />      
<resizeHandles val="rel" />
</varLst>                      

In this example, chPref is set to a single node and the user interface disables after a single node has been inserted. end example]
