The XML_ENTITY_REF_NODE should have children ptr == last ptr, pointing
to a XML_ENTITY_DECL, which can be cast to an xmlEntityPtr, I believe.

However, the parent of the XML_ENTITY_DECL will be the DTD, rather the
reference node, and its siblings will likely be other XML_ENTITY_DECLs
and comments etc from the DTD part of the document - this has caused me
no end of trouble when naively doing tree walks in Conglomerate :-(
