Yes i understood the two namespaces but i had not understood that the
proper domain is the one of the person who defines the tag. I had
the impression that everyone should use his own domain.

So, in the case of the issuer-fpr notation, which if i am not wrong
was introduced by Mr. Gillmor, the proper notation is
issuer-fpr at and not
issuer-fpr at my.domain.tld ?

Thank you for replying Mr. Shaw.
