@davidchisnall @nwf I haven't yet updated the semantics of sealing but hopefully you agree this is a correct first step. |

While the base CHERI specification only has unsealed capabilities and one type of sentry capability, other extensions (e.g. CherIoT) that will build upon the base CHERI-RISC-V standard have additional types of capabilities. Defining the specification in terms of object types instead of just having unsealed and sentry is one important step towards allowing CherIoT to be a RV32E extension on top of the base standard.
