More than one name for a function -- should this be allowed?

At present some implementations of EXSLT allow in addition to the
dash-containing official function name another, camel-cased name.

For example:

  nodeSet()

is supported by Saxon and XalanJ

but raises an error in 4XSLT, XalanC, MSXML4.

I think that allowing an alternate name for a dash-containing name must be
explicitly allowed or disallowed by EXSLT and this must be reflected in
the EXSLT specification.

In the current situation the existence of support for both types of names
has created a portability problem between the two groups of XSLT
processors above.

My personal position is that having two names for the same function is a
form of redundancy and bears with itself the disadvantages of redundancy.
