RE: user functions with variable number of parameters

Not quite what I want, need a little more logic.  I've ALMOST got it
now.  I've figured out that I can just use a normal untyped parameter,
pass it as a set, such as:

fn:myconcat(('abc', '123', 'def'))

In the function figured out to use for-each on the parameter, but now
trying to figure out how to tell which element # I'm on inside the
for-each, especially to detect the last item.  Also need to discard the
'current' item if it's empty, which I can't quite get.

string-join(expression, "
")

may already do what you want.
