[DFDL-WG] Non-format annotation scoping rules.

[Alan Powell]

Attached is updated proposal which incorporates Steve's comments..



The main issue to resolve is given that a variable can only be set once 
should a setVariable for the same variable on an element or element 
reference override the setVariable on a simpleType of element declaration 
or is it an error to have a setVariable for the same variable?

Other points of interest

Non-format annotations cannot be put in scope on a complex type.

[DFDL-WG] Non-format annotation scoping rules.







Attached are the proposed rules for non-format annotation scoping. 


 As part of the exercise I had to clarify which annotations are permitted 
on each schema object so please review that table. 
Of particular interest are 
1.      Annotations put in scope on a xs:complexType 
2.      Assert/Discriminator on xs:sequence, xs:choice and xs:any 
3.      Hidden on an empty sequence only 
4.      DefineVariable on schema and sequence only to define the scope of 
the variable.
