I'm really not at the point that I have understood you and disagree. I 
simply don't understand what you are saying.

Could you please give a concrete example, with angle brackets and code, 
that illustrates the problem? I agree that processing may impose semantics 
on data that was not envisioned by the creator of the data, but you seem to 
be saying more - that providing data types in XML data interferes with 
unforeseen reuse.

Please illustrate this with a concrete example.
