A document() reference with a #fragment selects a subset of the loaded document via XPointer; a node-set first argument unions the documents named by each node's string value; and a relative URI is resolved against a caller-supplied baseURI (the loader is wrapped so xsl:include/xsl:import resolve the same way). Closes the XSLT function/output audit.
