In developing XACML, we were advised that use of QNames made digital signatures on instances harder because the QNames might be resolved into different byte-strings by the signer and the verifier. In that case, the cryptographic hash will not match and thus the signature will not verify. I don't know enough about XML/naming to show how this would occur, but our XML experts told us to avoid QNames. Anne Jim Pruyne wrote On 07/12/06 03:58,:
