Add to that the fun bits like "let's attach a whole base64 encoded PDF as a field of the hl7 message". Which honestly is not a terrible solution given you want to keep it all together, but still... It would be nice if you could attach binaries after the ASCII content.

It is possible to include multiple binary attachments and text content in certain HL7 V2 message structures. Just use multiple OBX segments.
