Neat, Jeni. I observe that every time the web architectural design hits a snag by creating sharable objects that constrict the space of objects that can be shared, the same solution is adopted: to create a document type that declares the means of declaring the objects to be shared. There is a pattern here worthy of study if an only if it breaks through the glass ceiling of attempting to equate the names of things with the things we share. len From: Jeni Tennison [mailto:jeni@j...] A little while ago, Rick Jelliffe issued the challenge: > Personally, I think it is high time for people who don't like the > W3C datatypes to band together to make a concrete alternative. I thought I'd spend a little time on this, so I've put together a "datatype library language". The idea is that applications such as RELAX NG validators or XPath 2.0 processors could read in a document in this language and use it to construct a datatype library or set of in-scope type definitions. Note that this isn't a proposed datatype library -- it's not a replacement for the XML Schema datatypes -- rather, it's a language that enables users to create declarative definitions of the datatype libraries that they need.
