#385 Example for <ptr target="tel:..."/>

[stuart yeates]

On the mailing list I said that as per http://www.ietf.org/rfc/rfc3966.txt telephone numbers can be URIs in the tel: scheme, so <ptr target="tel:...">....</ptr> is a good place to start.

Laurent said there should be an example in the standard and I should create a ticket.

When fabricating an example, http://en.wikipedia.org/wiki/555_telephone_number suggests using and number in the range 555-0100 through 555-0199 which is roughly analgous to www.example.net in a domain name.

In discussion with Martin Holmes, we considered that <ref> might be more useful, so that you could include the transcription in the element as well as the normalized number in @target, e.g.

<ref target="tel:+1-201-555-0123">(201) 555 0123</ref>
or even:
<ref target="tel:+1-201-555-0834">(201) 5550 TEI</ref>

Would this be contained in addrLine, presumably?

[Lou Burnard]

If you click on a URI which is a phone number, presumably you intend to make a call?

[Martin Holmes]

@Lou: "clickability" relates to rendered output, surely, not encoding? I thought this was about how to encode telephone numbers in a standard manner.

Assigning to gabrielbodard to ensure an example gets into the Guidelines; Setting as Group: GREEN since seems uncontroversial to me, but check example with Council mailing list.

[BODARD Gabriel]

Added an example of telephone number using <ref> and the tel: namespace to both the element spec for addrLine and the prose at CONAAD [r12275].
