Just BTW, there is a TCG standard for a TPM 2.0 PCR mask that works well.
There is also a standard for an event log version number. It is the first event of a TPM 2.0 event log. It is strange.
One useful field, though, is a mapping between the algorithm ID (e.g., sha256 is 0x000b) and the digest size (e.g., 32 bytes). This permits a parser to parse a log even when it encounters an unknown digest algorithm.
