With the provider_search query in the CSD standard (with the new Change Proposals applied) we can perform validation
of a provider against a facility and service as:

<csd:careServicesRequest xmlns:csd='urn:ihe:iti:csd:2013' xmlns='urn:ihe:iti:csd:2013'>
  <function uuid='4e8bbeb9-f5f5-11e2-b778-0800200c9a66'>
    <requestParams>
      <id oid='2.25.309768652999692686176651983274504471835.646.1.615351552068889518564164611046405512878087'/>
      <facilities>
         <facility oid='2.25.309768652999692686176651983274504471835.646.2.12312321321'>
            <service oisd='2.25.309768652999692686176651983274504471835.646.3.9129312312'/>
         </facility>
      </facilities>
    </requestParams>
  </function>
</csd:careServicesRequest> 

The response will look something like:
  <CSD>
   <serviceDirectory/>
   <organizationDirectory/>
   <facilityDirectory/>
   <providerDirectory>
     <provider oid=''2.25.309768652999692686176651983274504471835.646.1.615351552068889518564164611046405512878087'>
      <!-- POTENTIALLY LARGE AMOUNT OF CONTENT ON THE PROVIDER -->
     </provider>
   <providerDirectory>
  </CSD>
on success.  On failure, it would look like:
  <CSD>
   <serviceDirectory/>
   <organizationDirectory/>
   <facilityDirectory/>
   <providerDirectory/>
  </CSD> 

Success Condition: encounter it is valid if and only if count(/CSD/providerDirectory/provider) == 1

 
Issues:
 -want to support more complex validation
 -don't need all the content

Proposal: in general, we allow the jurisdiction to use any stored query as a validation 
as long as it accepts the same parameters and returns a similar format.  Here XXXX could be any other stored 
query that meets these conditions.
