RE: [ann] Schema Lightener: a free tool for simplifying schemas

 > A full FAQ is available at http://www.xmlhelpline.com/tools (including a
section on how this relates to Schematron and other solutions). This is an
initial 1.0 release.  I would love to continue to improve it if people find
it useful.  
 
 
Other requirements for subsetting that I have often encountered include:
 
(a) reducing the value set of an enumeration
 
(b) changing minOccurs or maxOccurs values.
 
In general I quite like the idea of making this instance-driven, though I
can see that in some cases, creating instances that are sufficiently
representative could become rather tedious.
