While the two definitions that google turned up showed that functions as
first class objects are not necessarily part of the definition they both
do suggest that function definition _is_ part of the definition of a
functional language.
... "A language that replaces programming steps with function definitions" ...
... "using a functional language, you write functions to describe " ...
XPath does not have function definition capability and I think it fails
to meet either of these definitions of a functional language.
With Phil Wadler on the working group, we could hardly get away with using
the term in a way that's out of line with accepted definitions.
Perhaps he only had his eye on Xquery (or XSLT) which do of course have
function definition.
