+Setting pz:xslt may embed local XSLT as an alternative to referring
+to filenames.
+Value is not CDATA but XML nodes embedded, so escaping is not necessary
+but a root element *must* be present. For example:
+<settings target="target="z3950.indexdata.com/marc">
+ <set name="pz:xslt">
+ <xsl:stylesheet
+ version="1.0"
+ ..
+ </xsl:stylesheet>
+ </set>
+ </settings>
+
+Metadata field rank may given by XML internal document (pz:xslt
+result). If rank is not given, the rank from service description is
+used - as before.
