   Libxml2 generates only XML_DTD_NODE whcih are xmlDtdPtr. 
 XML_DOCUMENT_TYPE_NODE enum is here from DOM early cut'n paste but
never used. A DOCTYPE declaration is associated an xmlDtdPtr kept as
child of the xmlDocPtr (and also recoded in it with a direct pointer).
  But this can't explain why such a node was "magically" created,
why it has bad pointers in it, why it has an XHTML1 strict public ID.

 to me this does not make sense, at all !
