XML Schema in PLCS - P28 edition 2 support

The DIS version of part 28 edition 2 "ISO/DIS 10303-28e2, STEP Part 28e2, Implementation methods: XML representations of EXPRESS schemas and data" was published at the end of January.

This is a specification for deriving an XML schema definition from the EXPRESS models. It also defines the XML that PLCS will use for exchanging data.

Over the last few weeks Eurostep (Mike Ward) has put significant effort into modifying the XSL used to automatically generate the XML Schemas for the DEXs (and any other EXPRESS model) to accommodate the changes made to the standard.

The XSL has been checked in to STEPmod and is available in DEXlib (DEXlib just reuses from STEPmod).

Do a cvs update on:

stepmod\xsl

stepmod\dtd

This will then work in DEXlib and can be used to generate the XSD for DEXs.

Mike is also updating the DEXlib info section to provide some examples of some EXPRESS fragments, the corresponding P28 XML Schema, and an example XML fragment.

In addition, there is some example XML data provided in the 2410 business concept.
