The ESSSecurityLabel structure includes two INTEGER types:

  version Version DEFAULT v1

and
  security-classification SecurityClassification OPTIONAL

when an optional security classification is present, don't we have
a tagging problem within the ESSSecurityLabel SET?  Shouldn't one of
these INTEGER types include a context specific tag, such as

  security-classification [0] SecurityClassification OPTIONAL

I believe we do have an ambiguous tag situation, and would propose
that the security-classification definition be changed to include
a context specific tag as defined above.

Correct, the ASN.1 is ambiguous without the tag being present.
A change of the sort that you recommend is required.
