I suggest to add a reference (link) to the "HL7 Domain Analysis Model: Harmonization of Health Quality Artifact Reasoning and Expression Logic."

Existing Wording:

Focusing on the expression logic component and identifying the requirements common to both quality measurement and decision support, the Clinical Decision Support HL7 Work Group produced a harmonized conceptual requirements document: HL7 Domain Analysis Model: Harmonization of Health Quality Artifact Reasoning and Expression Logic.
