Would it be possible to clarify semantics of these permissions please?
The document says Authorize capability load via this capability. suggesting it is sufficient to have e.g. CHERI_PERM_LOAD_CAP to load capability. However, some other CHERI-related documents specify that CHERI_PERM_LOAD_CAP isn't effective without CHERI_PERM_LOAD. I'd appreciate a confirmation on which option should be considered correct for CHERI generally.
