RE: [xml-dev] Strategy for upgrading schemas to XML Schema 1.1?

["Costello, Roger L." <costello@mitre.org>]

Ah, excellent. Thanks Michael. So, here is a skeletal strategy for upgrading to XML Schema 1.1:

Step #1: Switch to an XML Schema 1.1 validator. Since a 1.0 schema is a 1.1 schema this change will have no impact.

Step #2:  Eliminate a processing step that's currently occurring after XSD validation (XML Schema 1.1 can do what you are currently doing in Java code or with Schematron).

Step #3: Do stricter/stronger validation than you are currently doing (there's lots of facilities in XML Schema 1.1 for this).

Step #4: Make your schema components more reusable.

Depends on your business objectives. For example, you might want to 
eliminate a processing step that's currently occurring after XSD 
validation, or you might want to do stricter/stronger validation than 
you are currently doing, or you might want to make your schema 
components more reusable.
