I think it's clear that the intent is that it should work, it would be
bizarre to allow automatic promotion from decimal to float (losing
arbitrary amounts of precision) but not to allow promotion from double
to float (losing a bounded amount of precision). Basically XPath works
as if there is a numeric type from which decimal/double/float are all
derived, and which if it existed would make many of these conversions
much simpler to specify. However it wouldn't be the first time that
there is a difference between what was intended to be specified and what
the specification actually says...
