OpenID status update

Is a middle ground to declare a version / protocol name with the current 
impl? An extra field, openid.version=1.0 or something to make the sig 
(in particular) less opaque like:
    openid.sig={DSAwithSHA1}MNalckcmw23429387492834....
or even:
    openid.sig={base64(DSA(SHA1(tokenV1)))}MNalckcmw23429387492834....

Debugging differently signed / encoded tokens will be horrific if they 
change later. It would be nice to avoid over time:
    openid.sig=MNsdfdfs
    openid.sig2=alkjdhcaldsakjd
etc
