Child Preference
This complex type defines how many children are inserted with a single action through the user interface to add a child. This is useful in hierarchy diagrams in which one would like to specify that every shape should have three children. A single click of the add shape button would add three children. The complex type is defined as follows:
<xsd:complexType name="CT_ChildPref"> <xsd:attribute name="val" type="ST_NodeCount" default="-1" use="optional" /> </xsd:complexType>
