[xsl] doc-available() using a caching EntityResolver on a CustomURIResolver

["andrew welch" <andrew.j.welch@xxxxxxxxx>]

Is it possible to give the XMLReader that receives the Source from a
CustomURIResolver a caching EntityResolver - Are then any examples
around?

Im using doc-available() a lot which is parsing the target doc and
fetching the entity files each time, I would like it to use the
caching EntityResolver that is used on the XMLReader that parses the
primary input XML.

thanks
andrew
