XPath 3.0 does so. It uses the syntax
"namespace-uri":local-name
rather than Clark notation to avoid conflict with another proposed use
of curly braces in XQuery.
I hope this form will become accepted in other contexts. I'd like to see
it allowed anywhere a QName is allowed, including element and attribute
names in XML. (It wouldn't be legal XML 1.0, but it could easily be
preprocessed into legal XML 1.0 for the benefit of parsers that don't
recognize it.) And then perhaps people will be encouraged to go for
short namespace names, like "w3c.xslt", that remove the need for
prefixes without significantly increasing the risk of name clashes.
