  Which is why I decided that xsltproc parameters would be
instead XPath expression, not strings. It requires a bit more
work to pass strings at the shell level ("'string'"), but 
there is no requirement for extensions in the stylesheet and
the full XPath expression power is available for parameter
evaluation.
