This is the final set of changes to the Conway CDDL spec made via comparison with the original cddl files for Conway. As of this commit, the remaining changes with the original cddl are as follows: - Various fields in crypto were defined with /= and are now defined with =. This does not affect the semantics, being instead a convention as per https://datatracker.ietf.org/doc/html/rfc8610#section-3.9 - The index keys in auxiliary_data are written as if they were value and not type keys: ``` 39,43c30,34 < / #6.259({? 0 : metadata < , ? 1 : [* native_script] < , ? 2 : [* plutus_v1_script] < , ? 3 : [* plutus_v2_script] < , ? 4 : [* plutus_v3_script]}) --- > / #6.259({? 0 => metadata > , ? 1 => [* native_script] > , ? 2 => [* plutus_v1_script] > , ? 3 => [* plutus_v2_script] > , ? 4 => [* plutus_v3_script]}) ``` This is a simpler formulation with identical semantics. - The alternatives in 'certificate', 'relay', 'native_script' and 'gov_action' are encoded using type1 choice semantics ('/') rather than group choice semantics ('//'). In the context, this is an equivalent formulation. - nonempty_oset has been removed, pending explanation of what it means. nonempty_set is used instead. - In various places, null is replaced with nil. They are synonyms. - The names of type parameters are changed; typically a is replaced with a0. - A few rules using references as the bounds in ranges are now inlined. This will be fixed once input-output-hk/cuddle#29 is addressed. - `distinct` is not currently possible to implement as a generic function, since `sized` is currently specialised to work on values. input-output-hk/cuddle#31 addresses. Until this is fixed, distinct<bytes> is instead distinct_bytes. - tstr is replaced with text. They are synonyms. - The keys in the 'pool_params' and 'script_n_of_k' groups are lost. This is due to input-output-hk/cuddle#32. However, since pool_params is included into an array, this does not alter the semantics, only the documentation. - datum_hash is of type datum_hash, not hash32. This seems an overlooked item in the original cddl.

Currently sized is specialised to operate on values:
This is nice in terms of preventing invalid use, but it prevents the use of sized on references, including on generic args where we might not know the suitability of the operator. So alas we need to liberalise it.
