Re: [stir] Renaming E164Number

["Peterson, Jon" <[e-mail]>]

No mutual understanding of the semantics is required by the authentication
and verification services here - though in practice, calls that are routed
to destinations via a dial string with a * or # in it should end up going
to fairly specialized pieces of equipment, and I'm actually less worried
about canonicalization and so on being an issue for special dial strings
like this than I am for ordinary E.164 numbers. We're not placing any
restrictions on where in the dial string those non-numeric characters
might appear, as there doesn't seem to be anything gained by doing so
except introducing complexity.

In terms of what to call it, if we can't agree on Freddie, I do think TN
or something similarly generic is appropriate. If we already have a group
field for TelphoneNumberRange, why wouldn't the base element be
TelephoneNumber? Or if we'd be overloading some existing registered name
by using that, like TelNum or something?
