Hidden groups are enabled by an empty local sequence with a dfdl:hiddenGroupRef property.
As such they are an example of an empty sequence.

  • Status changed from accepted to submitted

Changed back to 'submitted' status, as the specific wording and places requiring change are not clear to me. Our workflow is that things are submitted and move to accepted when we understand their resolution and its impact on the specification such that creating an actual Erratum is straightforward.

The comment above about sections 4.1 and 4.5 doesn't seem sufficient to me. Section 14.1 about Empty Sequence Groups seems to need to be updated to at least mention that <xs:sequence dfdl:hiddenGroupRef="..."/> is not considered to be an empty sequence, but rather a group reference. We should clarify if <xs:complexType><xs:sequence dfdl:hiddenGroupRef="..."/></xs:complexType> is legal or not.
