Let me clarify the XSLT point: XSLT defines functions such as current()
which are not in the XPath set.
Those functions are not prefixed. XForms and XSLT bear the same
relationship to XPath.

??? XSLT 1 mandates that all extension functions use qualified names
with
a non empty prefix. xslt 1 says:
If a FunctionName in a FunctionCall expression is not an NCName
(i.e. if it contains a colon), then it is treated as a call to an
extension function

In what way are they disallowed in XPath 1?
