How can I read the DOCTYPE SYSTEM identifier with Delphi?

For a document which has a DOCTPYE declaration like

<!DOCTYPE RootElement SYSTEM "file.dtd">

Delphi 2009, using MSXML, reports that the systemId is empty (""):

Assert(Doc.DOMDocument.doctype.systemId <> ''); // fails!

while 

Assert(Doc.DOMDocument.doctype.name = 'RootElement'); // ok

correctly verifies that the DOCTYPE name id "RootElement".

Is this a bug in Delphi (or my code) or am I using a version of MSXML which does not support this property?

MSXML's DocumentType implementation is completely missing the DocumentType properties publicId, systemId and internalSubset. MSDN api ref; the missing properties are specifically called out in MS-DOM2CX.

If you need this information you might have to try a different DOM implementation. Here's one. If you can use .NET classes, System.Xml supports it too.
