This is a detail that should be covered by the formal section.

Normative text in "3.1.1 INSERT DATA" isn't the right place.


4.3.1 Insert Data Operation

OpInsertData(GS, QuadPattern) = Dataset-UNION(GS, 
Dataset(QuadPattern,{},GS,GS))

4.3.3 Delete Insert Operation
...

4.4.1 Create Operation
OpCreate(GS, iri) = Dataset-UNION(GS, (iri, {}))

all go through "Dataset-UNION" so it looks like it already says that anyway.

So I think it already says it and in the right place.
