This topic is used to propagate signed inclusion list as SignedInclusionList.
The following validations MUST pass before forwarding the inclusion_list on the network, assuming the alias message = signed_inclusion_list.message:

• [REJECT] The size of message is within upperbound MAX_BYTES_PER_INCLUSION_LIST.
• [REJECT] The slot message.slot is equal to the previous or current slot.
• [IGNORE] The slot message.slot is equal to the current slot, or it is equal to the previous slot and the current time is less than attestation_deadline seconds into the slot.
• [IGNORE] The inclusion_list_committee for slot message.slot on the current branch corresponds to message.inclusion_list_committee_root, as determined by hash_tree_root(inclusion_list_committee) == message.inclusion_list_committee_root.
• [REJECT] The validator index message.validator_index is within the inclusion_list_committee corresponding to message.inclusion_list_committee_root.
• [REJECT] The transactions message.transactions length is within upperbound MAX_TRANSACTIONS_PER_INCLUSION_LIST.
• [IGNORE] The message is either the first or second valid message received from the validator with index message.validator_index.
• [REJECT] The signature of inclusion_list.signature is valid with respect to the validator index.
