Comment:

In the previous FHIR build process, when the FHIR source spreadsheet were processed, extension definitions at the resource or global levels were generated as separate structure definition files prefixed with the name 'extension-' (e.g., extension-patient-clinicaltrial.xml) and file names followed a clear name convention. Such conventions made it easy for tooling to use file filters to quickly identify extensions and process them accordingly. Now, the new tooling prefixes all the files with 'StructureDefinition-'. These filename thus no longer distinguish between extensions and other structure definitions forcing tooling to open the files, parse them, and check the type of structuredefinition first. I would like to suggest a naming convention such as the current one for the FHIR build tool that clearly distinguishes the type of structure definition in the file name.
