PRE_EVALUATE_DOC_FUNCTION (from http://www.saxonica.com/documentation9.0/javadoc/net/sf/saxon/FeatureKeys.html#PRE_EVALUATE_DOC_FUNCTION)
should be set to false so that XSLTs that use document function are able to
pick up changes eg. when using a metadata record from the catalog via
xml.metadata.get it is very desirable that the document function be evaluated
each time the XSLT is run rather than just once at compile time
Move schema list and status values list services into xml.info service
