CML development - Version 0.2 - 7/4/00 This document is the first draft of an XML Schema compatible with CML V1.0 published in JCICS... In converting the schema we have suggested some closed and some open content models. As CML develops it seems likely that there will be advantage in opening some of the models (e.g. angle), perhaps for annotations and ancillary information. Readers should note that the XML Schema activity is still at draft stage and that this schema may be revised in the future for compatibility. This schema is intended to be software and platform independent - we show in a note how it may be made to work with current implementations. XML documents can be validated against this schema by adding xmlns="x-schema:URL" within the cml element. Peter Murray Rust, Henry Rzepa, Michael Wright Comments to Michael Wright - karne@innocent.com
