While it's possible to find examples for how to perform a query in the core specification, having examples that are specifically tuned to the CDex use-case will aid implementers in understanding what's expected, particularly for those who aren't familiar with FHIR and the core spec.  We will undertake a review of all the examples and ensure that they're appropriately reflecting the CDex use-cases and are focusing on semi-complex scenarios so that there's clear value being provided.
