I agree that we should follow rfc 1630, and push for clarifications there if needed. In fact, why not simply inherit that spec rather than copy it into the URN syntax spec? If a URN is-a URI (it better be!), then URNs must inherit the URI constraints, although URNs can be more constrained. Tim B-L recently mentioned on the URI list that relative URIs may contain ";name=value;name=value" pairs in his original plans, but I don't know that this is actually followed in any practice, but the characters are still reserved unless explicitly unreserved. Instead, we see "?name=value&name=value" used for a similar purpose, but the structure after the '?' is merely a convention. -- Daniel LaLiberte (liberte@ncsa.uiuc.edu) National Center for Supercomputing Applications http://union.ncsa.uiuc.edu/~liberte/
