Overview

CombinedIdentifier represents CSA identifiers combined with "/" separator Examples:

CSA A23.1:24/CSA A23.2:24
CSA N285.0:23/CSA N285.6 SERIES:23
CSA A123.1-05/A123.5-05 (R2015)
CSA B44:19/B44.1:19/B44.2:19 (triple combined)

#root ⇒ Object

CSA combined ids are not Pubid::Identifier objects, so they do not inherit #root. They are their own origin for matching purposes.
