> Normative is just the adjective form of "related to norm"
You might want to recheck the definition of normative. Yours is a non-standard usage and you will be misunderstood if you continue to use it that way.
Norm is is, Normative is ought.
> Normative: pertaining to giving directives or rules
> Synonyms: prescriptive
No. Both definitions are correct. Don't tell people to recheck without first doing so yourself.
