I wouldn't say that it's silly. What I do say is that it makes no sense
to imagine that it would be used at the same time as named parameters.
The entire point of something like XMLELEMENT is that it takes a list of
undifferentiated parameters, which therefore do not need to have names
so far as the function is concerned.
