Thanks for this.  From the metadata-extractor documentation, it looks
like xmpcore.jar is required to have EXIF extraction work correctly, so
including it is fine.  I would suggest naming it xmpcore-x.y.z.jar
though (where x.y.z is the version number), and adding it to ivy.xml.

I don't see anything particularly concerning in the Xerces release
notes, but the only way to know for sure is to open a pull request so
that our continuous integration system can run a full battery of tests.

Regards,
