Topic: System value in Coding

So, if I want to say "Condition: Unstable angina, SnomedCT 4557003", which system value is correct in this coding? "http://hl7.org/fhir/ValueSet/condition-code" or "http://snomed.info/sct"

In more general term, for coding from external code system, such as SnomedCT or LOINC, should I use the value set URI or code system URI?
Grahame Grieve (May 30 2016 at 13:08):
Always the code system - see http://hl7.org/fhir/datatypes.html#codesystem: "The system is a URI that references the code system that defines the code. Choosing the correct system is important; for more information about the code system URI, read Managing Terminology System URIs. The system URI SHALL NOT contain a reference to a value set (e.g. ValueSet.url)."
Yunwei Wang (May 30 2016 at 13:17):
In the latest spec http://hl7-fhir.github.io/valueset.html, it states that "A value set can contain an in-line codeSystem, and/or". Is that still true? I thought in-line code system is now moved to CodeSystem.Concept.

yes, I need to hunt down and remove all that language
