[jdom-interest] Reading DTD error

[John]

Hi all

I have downloaded a DTD from the w3c web-site for MathML and XHTML:

http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd

When I attemt to parse a document using this DTD, I get an exception from org.jdom.input.SAXBuilder.build().

"Error in building: The markup declarations contained or pointed to by the document type declaration must be well-formed."

Any ideas? I assume this should be a valid DTD.
John

The stack trace gives:
