 Used when restoring attributes from the render region's context stack.Used when a render region needs to change a particular rendering attribute.This function provides a way of copying the contents of an AttributeValue derived class to another. It is assumed that the source object is the same class as the destination object. The data from the object pointed to by pAttr is copied into this object. This is primarily used when cloning render regions - the context stack must be copied, and if it points to any temporary objects, then they must be copied too, to avoid multiple deletion errors. Given an AttributeValue object, construct the appropriate NodeAttribute object which can be put into a document tree. This should be over-ridden for all derived AttributeValue classes, except those that cannot be put into the document tree (e.g. DrawingModeAttribute). The base class version (i.e. this one) will always ENSURE because it should not be called.
virtual BOOL IsDifferent (AttributeValue *)
