Updated CS Identifier process guidance

Continued from previousCarol

We are almost through the core principles. Will look into March for the next call as we were not able to find a time in Feb

The draft is located here: Validating and Requesting Identifiers for External Code Systems and Identifier Systems

HTA members and observers are asked to review the drafted text, directly edit where changes are needed and use the comment functionality to ask additional questions. We will review again (and hopefully approve on the next HTA call, which will be at the WGM).
