ifParameterExists and ifParameterNotExists?

Perhaps I'm missing something, but why doesn't Struts have
ifParameterExists and ifParameterNotExists tags? I'm writing some simple
Struts demos, and I've found a need for them.

ifParameterNotNull and ifParameterNull (respectively) have almost the same
functionality as what these tags would do -- the only difference would be
handling request parameters where the name was present but had zero length.
Is that close enough?
