I'm sure that everybody thinks that dotted-decimal strings in SIP URIs
are to be interpreted as decimal.  And for that matter, that series of
HEXDIG's are to be interpreted as hexidecimal.  Whether that is,
strictly speaking, syntax or not, I don't know.  But it appears that
neither of these facts has been stated in plain words, and in an
unpleasantly large number of situations, code may not follow that
convention.

As long as we're explicating the syntax, it seems reasonable to
enunciate what "everybody knows" about its interpretation.
