Re: DTDs and ANY

Martin,

I included thing.ANYs such that those things where we want to use extensible
content models can be easily tweaked. 

<!-- These entity declarations permit the flexible parts of Signature
     content model to be easily expanded -->

<!ENTITY % Object.ANY '(#PCDATA| SignatureProperties| Manifest)*'>
<!ENTITY % Method.ANY '(#PCDATA|HMACOutputLength)*'>
<!ENTITY % Key.ANY '(#PCDATA|DSAKeyValue|RSAKeyValue)*'>


The DTD including these entities (that I'm rapping into the next version) is
at:

http://policy.w3.org/WD-xmldsig-core-200003plc/xmldsig-core-schema.dtd

Thanks for your help!
