The telecom element is used in different classes of the CDA-RMIM to provide contact data of persons and organizations. It is defined by the RFC 2806.
To be able to distinguish between different types of communications, the @value attribute must contain as a prefix the identifier of the communication scheme, e.g. “tel”, “mailto”, … followed by an “:” and the communication URL.
If telephone or fax numbers are provided (“tel:” or “fax:”), they should contain the country code for which this number is valid e.g. “+352, +49, +33, …”. If the country code is omitted, the number provided is assumed as a number valid for the country related to the realmCode (see 3.3.1), which must be “LU” for documents which are conformant to this specification.
So the general layout is: “<communication_scheme>:<URL>”
The different communication schemes which are supported shall be from value set: eSanté_URLScheme.
