Hi,

What do you mean by "invalid url parameters" and "they don't mean anything"?
The spec allows one to specify any kind of uri parameter (other-param in the
ABNF syntax). Any implementation supporting the draft-yu-tel-url-04.txt will
treat them exactly the same way they would support them if they were in the
user-part, wouldn't it? They would only "mean nothing" to implementations
not supporting the draft...
