I do the following (C++):

  dtd = xmlParseDTD(NULL, dtd_path);
  if (dtd->name != NULL)
     xmlFree((char*)dtd->name);
  dtd->name = xmlStrdup(root_name);
  doc->intSubset = dtd;

  // Get rid of system id -- internal references only
  if (dtd->SystemID != NULL)
     xmlFree((char*)dtd->SystemID);
  dtd->SystemID = NULL;

  dtd->doc = doc;
  dtd->parent = doc;
  doc->children  = (xmlNodePtr)dtd;

  // Define and insert the root of the output document
  root = dtd->next = xmlNewDocNode(doc, NULL, root_name, NULL);

When the file is saved, it has the DTD embedded at the beginning of the file.
