 - The CDS Client MAY compute an efficient set of prefetch templates from multiple CDS Services, thereby reducing the number of calls to a minimum
 - The CDS Client MAY satisfy some of the desired prefetched templates via some internal service or even its own FHIR server.

 As part of preparing the request, a CDS Client processes each prefetch template it intends to satisfy by replacing the prefetch tokens in the prefetch template to construct a relative FHIR request URL. This specification is not prescriptive about how this request is actually processed. The relative URL may be appended to the base URL for the CDS Client's FHIR server and directly invoked, or the CDS Client may use internal infrastructure to satisfy the request in the same way that invoking against the FHIR server would.
