You can't create a node of NODE_DOCUMENT_TYPE. MXSML is not appropriate for creating a standalone DTD and I would simply create it as a string and save to file. So, I assume this is an inline DTD? If so, I would create it like so:

LOCAL lcXML AS String, loXML as MSXML2.DomDocument

TEXT TO lcXML TEXTMERGE NOSHOW PRETEXT 3
  <?xml version="1.0"?>
  <!DOCTYPE foo [ <!ELEMENT foo (#PCDATA)> ]>
  <!-- More DTD stuff goes here -->
  <!-- Add XML nodes here... -->
ENDTEXT

** ...Or here
lcXML = lcXML + "<foo>bar</foo>"

loXML = CREATEOBJECT("MSXML.DomDocument")
loXML.validateOnParse = .F.
IF loXML.loadXML(lcXML)
  ** ...Or here
ELSE
  MESSAGEBOX(loXML.parseError.reason)
ENDIF

Also, I would strongly suggest that you switch to XML schemas instead: it's XML(!), it supports more data types, and you can validate more complex structures.
