Hi all,

I have a question about the semantics of xenc:EncryptedData/@Type: Note the 
given examples. The root Element of the encrypted document contains an 
EncryptedData element with @Type="&xenc;Content" FOLLOWED by other content 
(a PI in the example).

Do I have have to flag an error if I try to decrypt (or encrypt) 
xenc:EncryptedData/@Type="&xenc;Content" which has siblings? Or should we 
specify that @Type="&xenc;Content" only means that the decrypted content is 
possibly not well-formed (which I would prefer).

Regards,
Christian
