Datatypes that require context to be correctly interpreted are a bad idea. I can't see much benefit but lots of harm form actually formalizing how to create more messes like QNames-in-content. > What is it about type hierarchies that you're wary of? They are unnecessary and can lead to difficulty in mapping them back to existing domain models. On the other hand, what most folks really want is just a way to specify type promotion or type equivalence rules. Most programming and query languages don't need an integer to be the derived type of a decimal number for one to perform operations involving both types or to use them interchangeably. -- PITHY WORDS OF WISDOM If putting your nose into other people's business doesn't work; try putting your heart into their problems.
