Classify a validation rule id into its namespace

Pinnacle 21 rule identifiers are namespaced by the artefact they police: SD#### SDTM data, AD#### ADaM data, CT#### controlled terminology, DD#### Define-XML and OD#### ODM / define metadata. Anything that does not match that shape is reported as "Other" rather than guessed at.

rule_class(rule_id)

Arguments

#> [1] "SDTM data"              "Controlled terminology" "Define-XML"
