CP: Dates for a health worker's posting should be captured

[litlfred]

There should be optional data elements to capture the expected start and end dates for a posting/associate of a health worker at a facility.

This particular use case came up in Ghana for community health workers -- as they are will be temporary contract employees, it would be good to be able to plan for turn-over.

More generally, this helps to answer the question of when there is the potential for a particular facility to provide a service. It is analogous to the operating hours of a facility.

Straw Man Proposal:

1. Add a new complex data type:

<xs:complexType name="operatingDate">
    <xs:sequence>
      <xs:element name="beginEffectiveDate" type="xs:date"/>
      <xs:element name="endEffectiveDate" type="xs:date" minOccurs="0"/>
    </xs:sequence>
  </xs:complexType>

2. Have the complex type operatingHours extend operatingDate

3)add an optional element operatingDate of type operatingDate under /providerDirectory/provider/facilities/facility

From my perspective seems like a reasonable element to support. I assume the "minOccurs" parameter of "0" indicates the "endEffectiveDate" is optional? (my sense is "endEffectiveDate" should be optional)

Per discussion on the Provide Registry group:
https://groups.google.com/forum/#!topic/provider-registry/OcLge1k6dcQ
This solution is proposed:

1. Modify the operatingHours data type so that dayOfTheWeek is minoccurs=0 and unbounded
2. Allow an operatingHours element under /CSD/providerDirectory/provider/facilties/facility
3. Declare more precisely how operatingHours should be interpreted.

For example when determining schedulable time for a health worker providing a service at a facility the following precedence rules apply:
-If any /CSD/providerDirectory/provider/facilties/facility/service/operatingHours exist, they take precedence over any of the other elements defined below. The other elements below are ignored.
-If any /CSD/providerDirectory/provider/facilties/facility/operatingHours exist, then they take
next precedence over any of the other elements defined below. The other elements below are ignored.
-If any /CSD/facilityDirectory/facility/operatingHours exists, then they are used for determine the schedulable time
-if none of the above elements exist, then it is assumed that there are no restrictions on schedulable time
