Fix Loading XML / DTD in TXMLDocument - DTD Is Prohibited

in TXMLDocument :: Delphi 2010 (and Delphi XE) uses MSXML 6 as the default DomVendor for the TXMLDocument. DomVendor (property) specifies the DOM implementation to use for parsing and manipulating the XML document.

In MSXML 6, the ProhibitDTD property specifies whether to prohibit (true) or allow (false) the inclusion of a DTD in the XML document. Prior to version 6, the ProhibitDTD was set to false by default. With MSXML 6, ProhibitDTD is true by default.
