-IMHO (as they write in English) I have not checked the status of XML schema the last 24 months. When I left the XML schema discussion Microsoft was trying to "order chaos" in their way while W3C was trying to unite various variants. >From both "camps" one of the "prerequisites" (as they say in English) - if not the most important prerequisite - was that the XML schema was itself written in XML 1.0. Hurray - the existing XML editors could fold and unfold the various XML schema variants. This idea - that the protocol description should be in the language of the actual messages on the line - I find this idea fundamentally wrong. The demands for a "proto" (or maybe the English would say "generic") protocol description are different: Intuitive, simple for simple examples, detailable to any depth the specifiers might wish (this means rich in ways of expression - in the language sense) and so on. I found then that ASN.1 comes closer to these goals. That even if all XML schema editors went together in one effort they would not come up with something useful because they started off the wrong place. I am not say that ASN.1 is the holy grale. Maybe some white-beards can come up with something more "generic" like a modified Bachus-Naur notation or the like. So where does all this lead ? In short: To cross-compile from ASN.1 to XML schema would require 1. Agreement on which XML schema version to end with 2. Extensions to XML schema to cater for the depth that ASN.1 has reached over the years - And this will be my final remark for now: This depth of ASN.1 could be what blocks a new generation of IT people to adopt. Keep the oddities but let newcomers have a go with a "recommended" subset - f.ex. one that would be enough to specify all-round XML protocols.
