Re: [ACTION-92] - Summary of all known algorithm identifiers for XMLDSIG

Thanks.

I think we should use the same base URI for all new items defined with 1.1.

To support DSA-SHA256, we would also have to update the DSA algorithm description in section 6.4.1 in addition to defining a new URI. The current description assumes 20-byte hashes.

It looks like we will need to define a URI for DSA-SHA256

would the following be appropriate for dsa-sha256 in signature 1.1:
http://www.w3.org/2009/02/xmldsig11#dsa-sha256
I assume we will also need URIs for key values. Which other algorithms
do we need URIs for?

Should we use the same base URI for Signature Properties and derived
keys to avoid too many new URIs?

Any comment or suggestions on the URI itself?
