Hi,

I have seen this in draft-ietf-rats-yang-tpm-charra-05.txt:

        leaf tpm-firmware-version {
          type identityref {
            base taa:cryptoprocessor;
          }
          mandatory true;
          description
            "Identifies the cryptoprocessor API set supported.  This
            cannot be configured.  However it is referenced via XPATH
            as part of configuration, so is shown as 'rw'
            to eliminate YANG warnings related NMDA.";
	}

I doubt that this is a proper solution as you now have to configure
the tpm-firmware-version. If you cannot configure this (as the
description says), then the MUST may always be false, i.e, once you
implement this, you will see that this does not work.
