[DFDL-WG] More schema work - I got inspired!

[Mike Beckerle]

Suman et al,
 
I got inspired by your XML Schema for DFDL annotations.
 
1) I fixed a few things in it. It is attached. I renamed it with suffix to
make it "...033-1.xsd"
 
You can diff it against yours to find the changes.  Some are: no 'all'
groups. Added dfdl:simpleType (which I think we forgot, but we need.) took
separator props off element and simple type, a few other cleanups. These are
a start on the version 034 changes.
 
Then I really got going....
 
2) I created an XML Schema for the DFDL subset of XML Schema
 
There is this XML Schema for XML Schema around. I subsetted it to match the
DFDL spec.
 
If you use this and your DFDL annotation schema together, under Eclipse,
it's really quite a reasonably electric DFDL environment.
 
I have a test file that uses all the annotations I could think of. 
 
So I've attached 3 files:
 
DFDL_v1_033-1.xsd - updated DFDL annotations schema
DFDLSubsetOfXMLSchema_v1_034.xsd - schema for DFDL subset of XSD
strictDFDLChecking.xml - example
 
The example is a bit tricky with the namespace prefixes - it defines the
"xsd" prefix to be the DFDLSubset schema, not the ordinary XSD schema. 
 
Anyway, I hope this contribution is helpful. It was kind of fun to do.

P.S., somewhere in the various archive files is a stylesheet that turns
short-form annotations on DFDL schemas into the longer form annotations. I
can dig this out if it is of interest.
