 Oh, is Gosling saying standards were accepted (by other people) before they are written? I took it to mean that he is claiming that standards have been accepted (by standards bodies) before they have been written. From: "Bullard, Claude L (Len)" <clbullar@i...> > Take a look at the Draft Federal Standard for > XML Developers. Note that it prefers W3C specs > over works from other organizations even if the > W3C specs are works in progress. So in a policy > document, the sort of thing Gosling mentions is > indeed happening. How do you get that? In http://xml.gov/documents/in_progress/developersguide.pdf it merely says that full standards must be used, and where there is competition, favour a W3C Recommendation. If there is a W3C Proposed Recommendation, you may decide to favour that if you commit to upgrading when the Rec comes out. "Ensure" is a funny word to use, and may have some American public service meaning, I suppose, but on the face of it, if there is no WXS REC in sight, you should fallback to another standard, and if there are no standards, you are then (naturally) in the province of proprietary or custom applications. They need to clarify. It also specifically mentions and allows ISO, ebXML and OASIS standards. Indeed, if there is an ISO or OASIS standard and a proprietary technology, people must choose the standard. Then it goes on to say "use XML Schemas" (unless you are continuing with SGML-ish DTD projects). This specifically shuts the door on using DTDs and RELAX NG for being the published structure definition languages for public schemas. It seems that Schematron (assuming it is accepted as an ISO standard) would fit in OK if used to augment a primary WXS schema. The mention of annotations suggests that embedded Schematron is OK too. In particular, it would not be a "proprietary extension" and could not be used to "define structures": instead it is providing (executable) documentation on things like links to external vocabularies and co-occurrence constraints, which are out-of-scope for WXS.
