Extension on Concept that points at Policy/Permission

[JohnMoehrke]

Given that the HCS vocabulary would tend to have a community assigned policy, should there be an extension on Concept datatype that can point at the policy / Permission?

For example:
Given an PurposeOfUse Treat, what is the definition of the policy allowed by a Permit on PurposeOfUse of Treat?

Question: Is there already a mechanism used to bind a lab procedure to a LOINC code?

Note that Medication (definition) goes the other way, in that it indicates the NDC codes it represents. So, should Permission have an optional element for the use-case of a Permission describing the rules for that code?

One solution is to define new codes everytime there is a need for a distinct code. The drawback of this is that it is not treating codes as concepts, but rather treating codes as policy identifiers. But lacking a need, this might be the best solution available right now.
