<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: 
<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 will disable after a single node has been inserted. ]
