Agree. Will make the following additions: https://hl7.org/fhir/us/cqfmeasures/using-cql.html#translation-to-elm Add option of "SignatureLevel" to the table. Description should state:  The SignatureLevel setting specifically controls whether the “signature” element of a FunctionRef will be populated. Recommendation should state : The SignatureLevel should be “Overloads” or "All" { }          2. Update cqlOptions ( https://hl7.org/fhir/us/cqfmeasures/using-cql.html#specifying-options)   to include recommendation for signature level. 3. Update conformance 4.23 to read: https://hl7.org/fhir/us/cqfmeasures/using-cql.html#elm-suitability If the library has function overloads (i.e. function definitions with the same name and different argument lists), the ELM SHALL have been be translated with a SignatureLevel other than  None ( recommend OVERLOADS )
