ANS1ExplicitContextValueConstructed fix things? I suppose that we could also,
if it makes sense, extend the ECV functionality to include handling multiple

Primitive/Constructed. I think what I am learning is that the
Primitive/Constructed is represented in the tag of a Triplet, but the
Explicit/Implicit is a property of the Type Module defining user types. We
don't have any representation of that, since we are wrapping it all in an
ASN1ExplicitContextValue.<o:p></o:p></span></font></p>
