It's actually here: http://trustedcomputinggroup.org/wp-content/uploads/TPM-Main-Part-2-TPM-Structures_v1.2_rev116_01032011.pdf It's around page 101, section 10.3 the TPM_KEY12 structure. That tells you what to encrypt and how to construct the encrypted part of the blob. It refers to other structures, so you end up doing a bit of a pointer chase through the document.
