[vhdl-200x] Protect tool - Key block clarification

I'm in the process of implementing the protect tool directives described
in the draft IEEE P1076-2006, section 22. I was looking for a
clarification on the key specification/key block (sections and

All symmetric encryption methods described in section use
Cypher-Block-Chaining, which requires an initial vector (IV) to start
the chain. My interpretation is that the encoded and encrypted text of
the key block must contain both the encryption key and the initial
vector, in that order with no space separating them. The format the key
and IV appear in is important for ensuring compatibility between
different applications. Is this interpretation correct?
