Yes - that is exactly what I thought it was good for, string literals.

It might be useful (and I agree that the above form would not be
suitable)

nope. Although you might make an assertion

data:text/plain;charset="utf-8",12
isValidLexicalFormOf
http://www.w3.org/2004/SchemaSimpleTypes/Integer/value/12

I think it is. Further, other types can be created that were not in
W3C XML Schema, a benefit of using URIs for them.
