RE: 2 questions about Relax NG: ID/IDREF datatype and whitesp
Dave also sent me that. To do otherwise would have been to give DTDs a longer lifespan. It confirms comments made on this list along the way about the necessity of creating minimal standards and really, minimal systems. KISSGodzRule: Any feature acquires a use case somewhere and becomes almost impossible to remove post hoc. As I sit here planning a 'features complete' release of a CAP-conforming health alerting system, I marvel at the truth of that. Here's something for you to ponder: what percentage of a database entity design (and consequently, supporting forms, business classes etc) should support domain-lookups (eg, metadata) vs operational data (ie, business data)? It's not a trick question but the answer affects product planning and standards planning. len From: Costello, Roger L. [mailto:costello@m...] So I conclude that, unless otherwise specified, a Relax NG validator will treat ID and IDREF values the same way that XML treats them, i.e. an IDREF value must reference an ID value. /Roger  http://www.thaiopensource.com/relaxng/jing.html -----Original Message----- From: Len Bullard [mailto:len.bullard@u...] The technical clarification will be interesting to read, but marketwise, given that ID/IDREF checking has been provided since ISO 8879 SGML, not validating that in a *validator* would be surprising even if not in the lexical parse. Assert: a tool can only be abstracted so far before it loses cohesion With the original application and user base. Don't shock the monkey. len From: Costello, Roger L. [mailto:costello@m...] Hi Folks, I am reading the "Guidelines for using W3C XML Schema Datatypes with RELAX NG", and am confused about a couple of things. QUESTION #1 This paragraph in the Guidelines discusses the ID, IDREF datatypes: The semantics defined by [W3C XML Schema Datatypes] for the ID, IDREF and IDREFS datatypes are purely lexical and do not include the cross-reference semantics of the corresponding [XML 1.0] datatypes. The cross-reference semantics of these datatypes in XML Schema comes from XML Schema Part 1. Furthermore, the [XML 1.0] cross-reference semantics of these datatypes do not fit into the RELAX NG model of what a datatype is. Therefore, RELAX NG validation will only validate the lexical aspects of these datatypes as defined in [W3C XML Schema Datatypes].
