I think this is where we differ. To me a type is just an assertion about data. 
That it properly constrains/validates the data it is almost orthogonal.

You may wish to call it documentation. Documentation can be very useful, notably 
when it's machine-readable.

In another post you state:

I think this is another point where understandings differ. Within the context of 
XML, I would consider what you call "the type _of_ XML" degree zero of typedness 
equivalent to the statement that "something is of type Thing", ie truistic 
metadata, pretty much useless as such and that can be considered as untyped.

Thanks, I'm looking into it.
