Thanks. I was a little confused when I couldn't find this looking at the
text version of bis03. Then I dug up this note from the SIP list:

This is a terrible error, and I apologize. There are three files that are
different between the text and ps/pdf versions of the document, and these
three are the syntax for the URL, contact and via headers. Somehow the text
versions have reverted to an older version; I am going to look into how this
happened (I suspect the CVS repositories we use for the spec did not contain
the latest version that was in use). I have gone through and have brought
them into sync, and this will be reflected in the -04 version. I will likely
issue this shortly so that people have a consistent version asap.

This is defined in the tel URL specification, rfc2806. This is referenced by
section 2.

The converted sip-url is correct.
rfc2543bis-03.ps and rfc2543bis-02 reflect
the addition of ';' as user-unreserved.
Thus it can appear non escaped within the
user portion of sip-url.
"+1-800-123-4567;cic=+1-6789" is the userinfo
portion of the sip-url. "sip.xyz.com" is the
host.
