If it's Element or Content, it tells you it's one of those structures. 
Otherwise the data is handed to the application with the Type/Value as 
advisory -- if provided. However, your question invites a question raised 
earlier as to whether the plaintext carried by an EncryptedKey is always 
the literal key value. I do think we need to provide some guidance 
regardless, but is anyone arguing against the possibility of a 
<PGPData><PGPKeyPacket>...</PGPData><PGPKeyPacket> as the 
plaintext data carried by EncryptedKey?
