If xmlTextReaderRead returns 1, then the XML is well formed.

For the short version, you'll get a XMLREADER_TYPE_ELEMENT. If you
call xmlReaderIsEmptyElement(), it will return 1. There will be no
XMLREADER_TYPE_END_ELEMENT.
For the long version, you'll get a XMLREADER_TYPE_ELEMENT
(xmlReaderIsEmptyElement() will return 0) and later a
XMLREADER_TYPE_END_ELEMENT.
