   xmlCtxtReadFile
    http://xmlsoft.org/html/libxml-parser.html#xmlCtxtReadFile
    options:    a combination of xmlParserOption
    http://xmlsoft.org/html/libxml-parser.html#xmlParserOption
    XML_PARSE_DTDVALID = 16 : validate with the DTD

 With that option xmlCtxtReadFile() will attempt DTD validation of the
instance.

  If there was no changes I would not have released a new version. Sorry
I never dig out ancien versions to check. You can check new versions,
it's your side of the job to check it c.f.:

  yes

  no. xmlValidateDtd is not the validation as defined by the XML REC it
does not handle the internal subset. On the other hand you have control
over what DTD is used.
