Perhaps referencing the Extensibility and Community beneficial points which have not been explained yet is not relevant? After all you make this a separate entry called "Fitness" so it has to be sufficiently well defined and should be shown to be well metched by the FHIR based model without referring to other attributes, especially if they are not yet formally defined.

Existing Wording:

This, in addition to the Extensibility and Community beneficial points listed below, holds much more opportunity and likelihood for much better “fitness” for semantic representation and ultimately valuable and actionable application of Quality Measurement and related CDS interventions and other CQI use cases such as Case Reporting and Knowledge Discovery.

Proposed Wording:

This tight bond with the existing clinical systems ensures good “fitness” for semantic representation and ultimately valuable and actionable application of Quality Measurement and related CDS interventions and other CQI use cases such as Case Reporting and Knowledge Discovery.
