When trying to validate a cXML file against the supplied DTD I get the error message
The parameter entity replacement text must nest properly within markup declarations.
on this line in the DTD
<!ENTITY % Object.ANY '|xades:QualifyingProperties|cXMLSignedInfo|Extrinsic'>
I know nothing about DTDs. Is this a problem with the DTD or the .Net parser?
(I can work around the error by replacing the text with an empty string but don't understand the implications)
