Data Types Issue 68: Text Telephone Number
Introduction
There is a business need within two NHS CFH domains to represent a number for a 'text telephone' (a telephone which is designed for use by the hearing-impaired).
Having posted a request for suggestions to the MnM list, it was suggested that the following format be used:
<telecom use="PUB" value="x-text-tel:01392251289"/>
I intend to follow this format and use the 'x-text-tel:' prefix, and I am proposing that this format be added to the TEL datatype in the next release of the specification.
As Lloyd McKenzie suggested in a reply to my question, this will prevent variations from being invented to represent the same thing.
