>
> While working on a large DFDL schema, ran into a problem where a group is
> being shared in 2 places.
> I get an obsure message at unparse time like this:
> "Unparser needed event for {}nackHeader but got (invalid) {}nackHeader"
> This element nackHeader is the element that appears immediately after *one*
> of the shared group references. The other one works fine.
> Making a copy of the shared group so that it is no longer shared eliminates
> the problem and is the workaround.
> I will endeavor to create a simplified scenario to reproduce.
