What should the fix be? Mike's claim is that rfc3261
violates rfc3986, yet rfc3986 is internally consistent
in that it requires IPv6 literals to be enclosed in "[" and "]",
viz:
IP-literal = "[" ( IPv6address / IPvFuture ) "]"
At the same time, rfc3261 is internally consistent in that
it requires IPv6reference to be enclosed in "[" and "]", viz:
IPv6reference = "[" IPv6address "]"
Furthermore, I don't think the intent is to produce SIP-URI (as
defined in rfc3261) from a URI (as defined in rfc3986), is it?
Note that rfc3986 defines URI as:
URI = scheme ":" hier-part ...
heir-part = "//" ...
If this was true, a SIP URI would need to be produced as:
sip://[2001:db8:10] ...
In other words, I am trying to understand what the exact
problem is before we try to figure out where to put the
fix in...
Thanks,
