The error from Jena when I try to reproduce is fairly clear:
@Test
public void testGraphBinding() {
MarkLogicDatasetGraph dsg = getMarkLogicDatasetGraph();
String updateQuery = "WITH ?g INSERT { <http://example.org/a>
<http://example.org/p> \"1\" }";
BindingMap updateBindings = new BindingHashMap();
updateBindings.add(Var.alloc("g"),
NodeFactory.createURI("http://example.org/g";));
UpdateRequest update = new UpdateRequest();
update.add(updateQuery);
UpdateAction.execute(update, dsg, updateBindings);
}
org.apache.jena.query.QueryParseException: Encountered " <VAR1> "?g "" at line
1, column 6.
Was expecting one of:
<IRIref> ...
<PNAME_NS> ...
<PNAME_LN> ...
So I guess to reframe my question -- given that the expectation of this
customer is that ?g should be bindable here,
can I give them a rationale? Sometimes "the spec prohibits it" is not what
people want to hear.

do you have a concrete example which you are in a position to share?
where did the customer express a binding for the ?g of which they thought the
‘with’ clause was in its scope?
