Reference to the Brown's draft

I have one question for XML-DSIG draft.

All W3C&IETF XML-DSIG web pages refer to the brown's IETF draft
(draft-brown-xml-dsig-00.txt). But there exists the the revised version
of his draft.
(Please see 
http://lists.w3.org/Archives/Public/w3c-xml-sig-ws/1999Apr/0051.html )
I think we should use the revised document as reference.

What do you think?
