> Today, the class SchemaCompatibility reports incompatibilities with quite little detail. The whole reader and the whole writer schema is listed, and no particular detail about what was incompatible.
> The attached patch fixes this, introducing a new enum (SchemaIncompatibilityType), and more specific sub-schemas that were incompatible.
> The old, overall picture, is still there - the new compatibility state is encapsulated in the SchemaCompatibilityDetails class.
> Lots of test cases have been added, and there has been refactoring done in the TestSchemaCompatibility and other test classes.
