How about having only one parameter containing name:value pairs,
and make an adapted tokeniser to turn it into a node-set? That way
you could use XPath on your parameters to find out which ones they
are as well as what value they have.

Just a suggestion - I haven't completely got my head round your problem
so maybe I'm missing the wood for a tree or 2.
