> EDIFACT uses sequences which have dfdl:initiatedContent="yes" but one or more of the child elements of the sequence is required, not optional.
> Daffodil appears to execute a discriminator=true behavior even for these required elements, which means the point of uncertainty being discriminated is some enclosing one, as the element itself in the sequence doesn't have one.
> The DFDL Spec clearly says that the initiatedContent only affects optional elements.
> The right thing is for a required child to ignore initiatedContent.
> If all children of a sequence are required and the sequence has initiatedContent, that should at least be a warning, because the initiatedContent property would then be entirely ignored. This case does come up in EDIFACT.
