Could be; it's just a trade-off, since you lose the built-in schema
validation by using a non-standard type attribute. I guess SOAP
processors can be taught to look for it, plus I know some of them don't
schema validate in automatic fashion anyway.

I think a wrapper or your suggestion are much better either way, but
then I have some sympathies with the XSD-centric approach to typing all
this stuff, so I'm biased against another type system in general.
