[XPS-announce] XPL Schema Released

Fellow extensible programmers,

I have (finally!) released the initial draft of the XPL schema
definition. The released files can be found on SourceForge.net at the
following location:

http://sourceforge.net/project/showfiles.php?group_id=51164 

There are two releases under the "XPL" package, XPL-en and XPL-Abstract.
In both these releases there are .gz, .xsd, and .zip files. The .xsd
file contains just the schema definition so that if you have a schema
browser (e.g. XML Spy), this is all you need to download. The .zip and
gz files both contain full (generated) documentation on the schema and
are provided for those of you who do not have XML schema browsers. 

The XPL-Abstract release contains the abstract syntax for XPL. Only
abstract schema elements are defined in this schema. Names of elements
are descriptive of their purpose with respect to the compiler. This
schema is not meant for programming but provides the abstract syntax of
the language and is the basis upon which the compiler is built. Each
element forms the head of a substitution group that is intended to be
replaced with appropriately named elements for the various natural
languages.
 
The XPL-en release contains the concrete English language version of
XPL. Other languages will come along as we interest international open
source developers in XPL. The XPL-en release contains only concrete
elements that are members of the substitution groups defined in the
XPL-Abstract schema. Consequently, XPL-en is dependent on XPL-Abstract
so you'll need both schema files to view XPL-en properly.

Your comments on this new language definition are welcome. However,
please note that this is a work in progress. If you wish to contribute
substantially to this language, please join the SourceForge project so
we can disseminate information more easily. Documentation and continual
refinement will continue through the remainder of 2002 at which time
another release of the language definition will be made.

Best Regards,

Reid Spencer
