I just pushed 2 commits to LO master that fix the problem you encountered.

The configuration of the custom XML filter packages works a little 
different compared to the built-in filters. The 2nd userdata parameter 
currently is just ignored upon importing a package.

The first patch supports importing (but not exporting) the 2nd userdata 
parameter, so you can use the saxon/j based xslt 2.0 aware 
transformation in your filter (but still requires manually editing 
TypeDetection.xcu).

The second patch adds a simple entry field that lets you edit the 
transformation service that should be used with your filter. If you 
leave it blank, the built-in service (currently libxslt) will be used, 
but you're free to enter any service, like the 
com.sun.star.comp.JAXTHelper thing that uses to saxon9/j internally.

The ui is really the simplest thing that could possibly work, and it 
doesn't do any input validation or whatever, but at least it's there.

If anyone could tell my how to include a simple help snippet for that 
input fields I'd gratefully write a line or two.

If you're in a hurry those patches should apply cleanly to a checkout of 
the 3.4.3 release branch, otherwise they hopefully make it into one of 
the upcoming releases.

Cheers,

Peter
