	When used for nodes that only have the automatic package attributes, the

	Derived classes need to override Rewind() to rewind to their first
	attribute, but also call the base class version. Furthermore they must
	implement CurrentCustomAttributeName() to return the current attribute's
	name and NextCustomAttributeName() to iterate to the next attribute and
	return its name.
