This is quite true.

Simon points out (and I hadn't thought of it like this until he said
it) that Schemas could solve this problem in certain situations,
because the type assigned by the schema can be carried around in the
PSVI.  Unlike Simon, I don't think this constitutes a conspiracy to
force people to use XML Schemas.  In any case, preserving type
information through transformations is error-prone to say the least
(see discussions about XInclude).

I believe it was a deliberate decision in XML Schemas to try and make
simply-typed elements and attributes as similar as possible in this
respect.
