#34 XmlTransform:regen check should include XSLT parm check

[Michael Sorens]

The XmlTransform tool performs an XML to XML
translation using XSLT on a directory tree, including
auto-generating navigation links and hierarchical
summaries. It tracks changes to the source tree as well as changes to the XSLT files to only regenerate files that need updating.

One item that should also be checked--but is not--is the list of XSLT parameters passed on the command-line. That is, if the source file has one of the command-line parms, and the target file instantiation for that parm is different, then the file should be regenerated.
