It usually comes back to cost recovery in the lifecycle . SGML CALS proponents argued for years for the advantages of markup in the long lifecycle systems and were proven right. In a short lifecycle message format (system outlasts or is more pervasive than data) where you can either throw it away or archive it, one gets back to form, fit and function debates. SGML wasn't used for protocols, so maybe this is a new wrinkle, but I suggest it is more related to archival so in that sense, the same advantages: recoverability and reusability. Addressing INTO a binary requires some tricks not used a lot since HyTime unless one is mapping to an abstraction. Ever since the SGML binary discussions (circa 93?), this idea comes up at least biannually. It is like aliens: if they are here, where are they? The binary requirements can be asserted but one soon discovers that versions exist, none have been adopted widely and begins to ask why. The answer is usually that all other tradeoffs and conditions accounted for, there isn't enough cost benefit to justify adding yet another format to the support soup. Do protocol requirements offer a more compelling case than short lifecycle documents (where WYSIWYG turned out to be a good idea over markup: final fixed format vs archival format)? That said, press on. It's like a soap opera where one waits to see if the new character is good or evil: great entertainment but the plot remains the same.

Dayadhvam.h -----Original Message----- From: Miles Sabin [mailto:MSabin@i...] True in the document world, perhaps. But not so obviously true in the protocol world. For example, DNS question and answer payloads are an example of an open, structured, binary format. There are many others.
