	This is all very reasonable. I think I'm missing something here in regard
to what you mean by the term 'local scope'. Would this problem be solved by
the use of the dt:dt attribute e.g.

	<Amount dt:dt="i2">34</Amount>

	<Amount dt:dt="float">34</Amount>

	In fact, this is my biggest problem with using attributes to hold property
values: how ought these values be themselves typed?
