[ISO/IEC 29500-1 1st Edition]

chMax (Maximum Children)

This element is used to indicate when to enable and disable the user interface components associated with adding a new shape to a diagram. This element defines a max number of nodes a diagram can support through the user interface directly.

[Example: Consider the following example of chMax usage in DiagramML:

<chMax val="5"/>             
<dir val="norm"/>            
<resizeHandles val="exact" />

In this example we define the user interface to only be enabled to insert five nodes. end example]
