Could w3c-xml-sig be made public?

I am having an argument about error handling with some people and I 
wanted to point at the literally months of debate that went into the XML 
error-handling policy.  It turns out that that w3c-xml-sig is 
member-only.  This is an incredibly valuable archive, I think, and a 
huge number of the participants were non-members anyhow, and I can't 
actually recall why it was member-only at the time.

Anyhow, would there be any chance of making this publicly visible? 
Among other things, it would help me out in some of my curent work.
