On the contrary, I'd say that only those folks who are concerned with binary goo are concerned with encodings. Folks that deal with text, i.e. XML, don't generally have to be concerned (to a significant extent) with encodings, which is the *big win* of XML. > This is, of > course, downright baffling for the binary folk.

Right, so you could care less whether a number is encoded either: 1) big endian floating point 2) little endian double 3) big endian 64 bit integer etc. etc. etc. XML could really care less about these binary details. XML could just as easily deal with 203bit integers as 23 bit integers. These binary details just don't matter. > I want highly efficient ways for expressing my > "intent" which minimize the amount of effort that I must put into even > understanding mechanisms like encoding rules.

Right, so just deal with text and be done with all these trivial concerns about byte order etc. > My code presents an abstract object to an > interface which then serializes the thing in what I hope will be a > compact and efficient manner. The crux of the issue is whether you are more concerned with being: a) abstract "high level" b) bitwise efficient The only reason to be concerned with binary goo is if you have an overriding concern regarding "efficiency" > I really don't want to know how the bits > actually look while on the disk (unless I've got some debugging to > do.)

Do you mean an API that accesses some representation of an Infoset? Are you really talking about the DOM? Nothing against the DOM, but I don't use that much in the XML applications I've developed. Mostly I use XSLT to transform XML either submitted via HTTP and/or located on a server, and return the result back via HTTP. What is cool about this is that my applications *are* implementation dependent, as they run under Windows NT...XP, FreeBSD, Java etc. Haven't we met your goal of separating "interface" from "implementation". Certainly the infoset is important to this process as the infoset as exposed by the XPath model, allows me to write my XSLT so that I've got a clue what results to expect. What does this have to do with binary encodings etc? What does "encoding syntax" have to do with any of this? Jonathan
