REXML::Functions.name() is defined because name() is an XPath function, and=

REXML evaluates XPath functions using reflection.  While this behavior may=
=20
change in the future as a result of performance issues, currently that's ho=
w=20
it works.  The same goes for id().

While this may be poor form from an aesthetic view, it has very little=20
practical impact; nobody should be using the Functions class except the XPa=
th=20
module.  If a programmer does choose to use the class, then caveat lector. =
=20
In fact, if there's any argument about the Functions class, it is whether t=
o=20
make the entire thing private to REXML, rather than whether to rename metho=
ds=20
so they don't conflict with expected behavior.
