Subject: Move openurl stuff to marc21-ourl.xsl. Hookin marc21.xsl.
X-Git-Tag: v1.1.0~25
X-Git-Url: http://sru.miketaylor.org.uk/cgi-bin?a=commitdiff_plain;h=8620c6720a870accef9edded421382d303ead104;p=pazpar2-moved-to-github.git

Move openurl stuff to marc21-ourl.xsl. Hookin marc21.xsl.

The marc21.xsl now has a template record-hook which allows marc21.xsl to
be imported and record-hook to override stuff. The marc21-ourl.xsl
uses this facility and includes the pz2-ourl-marc21-xsl.
