I think we should use standard last call boilerplate. If it isn't  
ready for last call then maybe we should wait.

I think wsig: is clearer to the reader so would not like to do this one.

I suggest we remove "Trust in a certificate is established through a  
security critical mechanism implemented by the user agent, which is  
out of scope for this specification."

Mark, do you have a better suggestion?

there are only 7 steps, less than a page. I doubt it will get lost. I  
suggest leaving this alone. ok with dfn.

I think  the english "XML Signature" which I though makes it more  
readable. I guess we have different styles in mind, I prefer english +  
Reference, alternative is reference only. I can make this change for

how about

The signer uses the dsp:Identifier signature property to
uniquely identify the signature to enable signature management.

(you don't like passive voice? :)

The signer  SHOULD NOT generate signatures using key lengths of less  
than 2048 bits unless the life time of the signature is less than one  

By the way, shouldn't this be a MUST NOT?
