The IlvMapCompositeStyle class
The IlvMapCompositeStyle class does not define
any additional attributes. Its attribute list grows with its
child list.
When adding a child style in a composite
style, all the attributes of that child are added (if they did
not exist) into the parent style. Those values can then be
inherited for each child style – allowing the attributes for all
children to be changed in one single place.
You can change the inheritance setting of each attribute by
calling the setInherited method.
