All As requested I have updated Suman's element and group reference examples for the new scoping rules. It has highlighted some concerns We haven't really defined the scoping rules for dfdl:ref but they are assumed to be 'merge with local property definitions. Local takes precedence' dfdl:ref to defineFormat blocks are very difficult to use with parameterization. A dfdl:ref on an element/group reference probably has no effect. The properties would need to be converted to dfdl:setVariable . A dfdl:ref on a global element/group declaration is OK but any property that needs to be overridden must be defined locally as a variable. There is no easy way to provide a default for properties on global elements/groups that can be overridden. Suman had done this in his examples.

We did not discuss the rules for simpleType derivations so I have assumed that it uses the same rules as simpleType reference, namely that the properties are merged and there must not be any duplicate properties specified. I have removed most of the complicated examples as they no longer apply.
