The markup declarations contained or pointed to by the document type declaration must be well-formed.

[John.Ling2]

Hello,
 
I have an XML document which has a DOCTYPE tag referencing a DTD.
Instead I want to reference an XSD which specifies this document
structure.  I use the XMLCatalogResolver to detect the publicId in the
DOCTYPE and replace it with a URI pointing to the XSD.  I think this
part is working, however I get an error during the sax parsing:  "The
markup declarations contained or pointed to by the document type
declaration must be well-formed."  I believe the XML is well-formed
because if I omit the DOCTYPE tag from the XML document the parsing
occurs without error.  The namespace in the XSD is
"http://www.ncbi.nlm.nih.gov"; and I don't have any reference to
namespace in the XML document.  Is this what the error is refering to?
