RE: [dita] W3C XML Schema 1.1

["Tsao, Scott" <scott.tsao@boeing.com>]

Eric,

Thanks for the reply.  I noticed that this feature has been included in
the XML Schema 1.1 requirements (see
http://www.w3.org/TR/xmlschema-11-req/#N40014F).  However, since we are
using the W3C XML Schema 1.0 spec (not DTD) for most (if not all) of our
XML projects at Boeing, I am concerned if we are taking a major risk to
adopt DITA today before the following events actually happen:
1) W3C releases the XML Schema 1.1 Recommendation
2) DITA incorporates the needed feature(s) of XML Schema 1.1

Please help us better understand the potential risks.

Thanks,

Scott

Hi Scott,

The issue related to "restriction via subsumption" is still active
within the XML Schema WG.

RQ-17 -
http://www.w3.org/XML/Group/2002/07/xmlschema-1.1-current-reqs-list.html
#restrictn-rules
 (not sure if you have to be a W3C member to view the document).

I did speak to IBM's rep on the workgroup and he's is aware of our
requirements as well as the WG. They working on solving this issue for
WXS 1.1. Part of the new algorithm is implemented in Saxon 8.0 and XSV

Kind regards,
Eric

I recall that someone has mentioned that DITA requires functionality
beyond the current XML Schema (1.0) spec, and I wonder if those
requirements have been documented somewhere and are being considered by
the W3C WG to be included in the XML Schema 1.1 spec.
