namespace problem

Hi - 
I'm having a problem with namespaces:

Unknown element 'dsig:Signature'

where DTD is :
<!ELEMENT Signature (SignedInfo, SignatureValue, KeyInfo?, Object*)  >

<!ATTLIST Signature  

 xmlns CDATA #FIXED 'http://www.w3.org/2000/02/xmldsig#'

 Id   ID #IMPLIED >

and 
XML is 

<dsig:Signature xmlns:dsig = "http:etc...
it doesn't like the first element having the namespace in front of it...

this xml/dtd should be correct by the namespace standard...

any ideas?workarounds?what_i_did_wrong?

im using the ibm version xml4csrc3_1_0 on NT4

XML4C version 3.1.0 incorporates Xerces-C version 1.1.0 which is made
     available under the Apache License.

Thnaks very much,
OWen

No, it's not, since DTDs are part of XML 1.0 which _predates_ 
the namespace standard. So you have 3 choices: no validation, 
using schemas (but there is lack of support currently), or 
using fixed prefixes in you DTD.

The 3rd is the usual path taken.


Ciao, Jürgen
