[DFDL-WG] Scoping V8

[Alan Powell]

That was a quick response.

This is trying to cover the case where you have, for example, 
dfdl:escapeSchemeRef defaulted from the dfdl:format on the xs:schema and 
defined locally.

The dfdl:escapeSchemeRef defined locally overrides the 
default.dfdl:escapeSchemeRef rather than the properties in the 
dfdl:defineEscapeScheme/dfdl:escapeScheme referred to locally overriding 
the properties  in the dfdl:defineEscapeScheme/dfdl:escapeScheme from the 
default dfdl:escapeSchemeRef.

What this means in practice is that each 
dfdl:defineEscapeScheme/dfdl:escapeScheme must have all the required 
properties. We don't merge the local 
dfdl:defineEscapeScheme/dfdl:escapeScheme with the default 
dfdl:defineEscapeScheme/dfdl:escapeScheme

>> The dfdl:escapeSchemeRef, dfdl:textNumberFormatRef, 
dfdl:textCalendarFormatRef provide a default reference to a 
dfdl:defineEscapeScheme, dfdl:defineTextNumberFormat and 
 >> dfdl:defineTextCalendarFormat respectively. The properties of 
dfdl:escapeScheme, dfdl:textNumberFormat and dfdl:TextCalendarFormat are 
not defaulted individually. 
Alan - this is somewhat confusing..  The value of dfdl:textNumberFormatRef 
contains a QName to dfdl: textNumberFormat..   What does the default 
reference mean in this context ??

Although the scoping action was closed on the last call some updates to 
the proposal were needed after the discussion between Steve and I . 

The main update is to change the emphasis from scoping annotations to 
scoping 'representation properties'. This is because  1) the 
non-representation properties (ref and selector) are not defaulted or 
combined and 2) the same property may come from different annotations. 

I have also clarified the scoping of refs to escapeSchemes etc.
