Existing Wording: In FHIR, an eCQM is represented as a Measure resource containing metadata (the rest of this section) and terminology (Section 3), a population criteria section (Section 5), and at least one Library resource containing a data criteria section (Section 4)

Comment:

Section numbers (and some of their names) are outdated. They seem inconsistent throughout the IG too (e.g. Section 3-thru 5 appear both on the eCQM page and repeat in other pages).

Summary:

Fix section numbers
