<!--
	 This xslt stylesheet generates the Solr doc element consisting of field elements
     from a FOXML record. 
     You must specify the index field elements in solr's schema.xml file,
     including the uniqueKey element, which in this case is set to "PID".
     Options for tailoring:
       - generation of fields from other XML metadata streams than DC
       - generation of fields from other datastream types than XML
         - from datastream by ID, text fetched, if mimetype can be handled.
