As such they are an example of an empty sequence.

This should be covered by section 4.1, which can refer ahead to section 4.5.

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.

Suggested resolution here is to go with conservative language principle and continue with the restriction that the model group of a complex type cannot directly be a hidden group ref.
Proposed Erratum:
Section 14.1 is updated with this additional paragraph
A hidden group reference is indicated in DFDL using an empty sequence such as <xs:sequence dfdl:hiddenGroupRef="QName"/>.
To XML Schema this is an empty sequence group; hence it is an SDE if this appears as the model group of a complex type. Otherwise this is not considered an empty sequence, but a group reference.
