[Kissman, Paul (BLC)]

Adam,

Thanks very much. The patch worked perfectly. And you are right. I no
longer need to import str.xsl.

Think so. Attached is a patch for Pazpar2 1.0.13. Using that you should
not need import of str.xsl.

Guess it's also possible to download
http://www.exslt.org/str/str.zip
and import that. But have never tried that approach.
