XSLT cannot return a document node to eXist-db XQuery #2096

Returning an <xsl:document> from transform:transform actually causes eXist-db to return an XDM element(), it should instead return an XDM document-node().

document-node handling is repeatedly creating problems it seems. see #1964, #1932, #1562, …

Yeah, it seems our in-memory DOM is basically broken and has been for a long time. I think it was based on an old version of Saxon's TinyTree, and then modified. My plan is to bring over the latest version from Saxon as soon as I can.

If I remember well, one of the developers, years ago, commited some code that removed all document-node handling...
