Hi Loa,



Yes, agree, the framework document must be solution independent. It can be
used to specify the “considerations” for various options for actions (e.g.
opcodes vs. bit catalogues), indicator labels, ancillary data, etc.
However, IMO it must not suggest which option to use for a specific
solution, as it will be up to the solution draft.



Thanks,

Rakesh
