XML 2001 Schema Panel Invitation

 1 |At XML 2001, we plan to present a schema language comparison panel. Our
   |goal is to provide attendees with some idea of the relative strengths
   |and weaknesses of the schema languages that are currently available.  At
   |present, we plan to compare SGML/XML DTDs, W3C XML Schemas, RELAX NG,
 5 |and Schematron.
   | 
   |We would like you to lead a group of experts for <schemalanguage>. Once we
   |have found leaders for all the groups, we will announce the panel on
   |XML-DEV. Leaders are free to invite anyone they wish to join their
10 |group.
   | 
   |Each group will have three tasks:
   | 
   |1. Invent or adapt a document type of their own choosing, provide a
15 |   description of that doctype, and provide at least two valid
   |   instances. The goal is to allow each group to show off the best
   |   features of its language. All groups will be given copies of all
   |   the submitted doctypes.
   | 
20 |2. Provide a schema for a document type of the analysts choosing. The
   |   group will be given a complete description of the document type and
   |   a small set of valid and invalid instances. The goal is to allow
   |   the analysts to compare apples-to-apples as much as possible.
   | 
25 |3. Provide a schema for a small variation of the previous schema, as
   |   described by the analysts. The goal is to show how the various
   |   languages handle extension and modularity.
   | 
   |Each group must provide a schema for all three work items.  They may
30 |provide schemas for as many of the other groups doctypes as they wish.
   |All groups will be given copies of all the submissions. [Deadline, Nov 15]
   | 
   |The analysts for this panel will be Norman Walsh and John Cowan.
   | 
35 |They will examine each submission, consider how well it matches the
   |definition and the document instances, and prepare a report containing
   |their observations.
   | 
   |At the conference, there will be an evening of panel discussion (precise
40 |details to be arranged, of course). The analysts will present their
   |report, give the groups a chance to comment on the report, and give the
   |audience a chance to ask questions. The report will be circulated to the
   |groups before the panel discussion.
   | 
45 |Please let us know by August 24th whether you will be able to be a group
   |leader. If not, would you please suggest someone else who might be
   |interested, and also let me know whether you are interested in
   |participating in the group.
   | 
50 |We're open to suggestions for improvements, of course!
