That is not how I read the last sentence:

I don't understand "ignored" to mean "not match", i understand it to
mean "act as if that component is not in either URL".
Eg: I am comparing sip:[EMAIL PROTECTED] and sip:example.com . In this
case, the user field is not found in both URLs, and user has no default
value. Thus, the user field it is to be ignored. the resulting URLs
(after "ignoring" the user field) are sip:example.com and sip:example.com,
which are equal.
I don't disagree that this is nonintuitive--that's why I flagged it.
