(Corresponds to GPIC Common Access Group) Locator for some resource (information or services) mediated by telecommunication equipment The responder of a telecom address may be an automatic service that can respond with information (e.g., FTP or HTTP services). In such case a telecom address is a reference to that information accessible through that address. A given telecom address value may have limited validity through time and may be tagged by a use code to indicate under what circumstances a specific telecommunication address may be preferred among a set of alternatives. The telecommunication address is an extension of the Universal Resource Locator (URL) that specifies as an Internet standard RFC 1738.
