Hi,

Yes, I hadn't read that part of the spec but after reading the relevant
section which I think(??) is [1] I believe you are correct. The
topLevelComplexType seems to be missing the attribute wildcard. Maybe someone
else has some more info about this?

Cheers,

heading: "Complex Type Definition with simple content Schema Component" under
{attribute wildcard})
