Another technique I use is to pass in a string that is well-formed xml,
and then use the saxon:parse() extension to turn it into a nodeset.

A different technique is to take your source xml and modify that to
include the parameter markup before it gets parsed, wrapping the whole
lot in a new root:

<root>
	<param_array>..</param_array>
      ..
      orignal source doc
      ..
</root>

You can then access the parameter info as part of the input XML.
