\defineXMLpush actually makes its definition when the pushed element
occurs. When a parent element defines a group, then the pushed element
is not visible outside that group. In \TeX\ this problem is usually
solved by doing a \gdef. Perhaps this problem can be solved in the
same manner, by providing a \gdefineXMLpush.

See attached example.

\type{\defineXMLpush} actually makes its definition when the pushed
	element occurs. When a parent element defines a group, then the
	pushed element is not visible outside that group. In \TeX\ this
	problem is usually solved by doing a \type{\gdef}. Perhaps this
	problem can be solved in the same manner, by providing a
	\type{\gdefineXMLpush}.

In the example below the affiliation is output within the alignment
set up by author (marked by 1:), but not outside of it (marked by 2:).
