NDR Review - Section 7.7

[Grimley Michael J NPRI <GrimleyMJ@Npt.NUWC.Navy.Mil>]

Greetings,

I know we are not currently going to reconsider decisions already made; however, we do have to change the explanatory text around the xsd:choice rule (Section 7.7 - GXS9). It currently reads:

==================================================
The xsd:choice compositor allows for any element declared inside it to occur in the
instance document, but only one. As with the xsd:all compositor, this feature is
inconsistent with business transaction exchanges and is not allowed in UBL.
==================================================

I don't think this is true. As I had mentioned on yesterday's call, because an xsd:choice element can be contained within an xsd:sequence, it leads to no more uncertainty/variability in an instance than a "minOccurs='0'" does; therefore, I don't believe it is "inconsistent with business transaction exchanges".

Comments?

Thank You,
Mike Grimley
