yyyy is the year
mm is the month
dd is the day
hh is the hour
mm is the minute
[+|-ZZzz] is the time zone offset in hours and minutes

At least the year must be present.

Sections from the right of this representation may be left off when the sending system does not record to this level of accuracy. When hours are present, the time zone offset must also be present.

If a single point in time is to be carried the Date or Time Point data type shall be used:

The XML attribute value of the XML element center shall be populated with a time stamp

This datatype is used if date of the service is not fully known / available

If both a 'start date' and an 'end date' are present the Date or Time Interval Complete data type shall be used:

The XML attribute value of the XML element low shall be populated with a 'start date' time stamp

The XML attribute value of the XML element high shall be populated with an 'end date' time stamp

The XML attribute typeCode shall contain a value from the x_ServiceEventPerformer vocabulary.

The recommended codes for populating the XML attribute typeCode are listed below:

Code	Name	Definition
PRF	performer	A person who actually and principally carries out an action. Need not be the principal responsible actor, e.g. a surgery resident operating under supervision of attending surgeon, and may be the patient in self-care, e.g. fingerstick blood sugar. The traditional order filler is a performer. This information should accompany every service event.
PPRF	primary performer	A primary performer is a type of performer that represents the principal or primary performer of an act that involves other performers or assistants. The primary performer is the person who undertakes the primary activity not the most senior person involved.
SPRF	secondary performer	A secondary performer is a type of performer that represents a person who assists in the performance of the act. A secondary performer must be directly involved in the act. The term secondary performer relates only to the nature of participation in the act. Neither job title nor seniority has any bearing on whether a participant is a primary performer or secondary performer.

[1..1] [M] contentId (II) { "NPFIT-000091#Role" }
