Unique id for inter-element referencing
Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.
Additional content defined by implementations
May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
phone | fax | email | pager | url | sms | other
Telecommunications form for contact point - what communications system is required to make use of the contact.
The actual contact point details
The actual contact point details, in a form that is meaningful to the designated communication system (i.e. phone number or email address).
Additional text data such as phone extension numbers, or notes about use of the contact are sometimes included in the value.
home | work | temp | old | mobile - purpose of this contact point
Identifies the purpose for the contact point.
Applications can assume that a contact is current unless it explicitly says that it is temporary or old.
Specify preferred order of use (1 = highest)

Note that rank does not necessarily follow the order in which the contacts are represented in the instance.
Time period when the contact point was/is in use
Time period when the contact point was/is in use.
