A020 currently includes audio/basic (.au files) and audio/mpeg (.mp3 files) as valid media types: do we know if anyone is actively uploading files of these types in production?
It also includes MPEG Video (video/mpeg) - .mpg, .mpeg, .mpe: are files of this type actively being uploaded to attach to referrals in production eRS?
Also, xml files can be uploaded as attachments to eRS messages, but without knowing the application for these xml files, it is difficult to know how to render them in a readable format (other than to present them as raw xml with no style or formatting information). Do we know what applications these xml files originate from (e.g., FHIR QuestionnaireResponse, other NHS API, etc?)
