Only partially useful, I'm afraid.  IME, as you look through the (nee results, you eventually get to the point
where it's made a 'match' by finding parts of the search term in different
places in the one file, so the results are more useful for relative
popularity than for absolute numbers.

Implementing the full API was only ever at the bottom of my list [14].

Which is to say that you wouldn't want to emulate the libxslt functions
that take a xsltStylesheetPtr, but you could cover a lot of cases by
having similar functions that just take a filename or a xmlDoc for the
stylesheet and keep the other parameters more or less the same.

You also couldn't usefully fake a xsltTransformContext [15] either.  I've
only used that in anger for extension functions/elements, and they
wouldn't work with Saxon/C anyway.

Should we take this to the Saxon list before we're asked to take it off
this list?
