    Description

      Analysis of a memory snapshot with vendor models shows we end up with a SchemaContext which weighs about 240MB. Further analysis of duplicate objects shows we have 27257 instances of ModelDefinedStatementDefinition, which have the same QName and same yinElement – and waste ~600kB. They are reachable via UnknownStatementImpl, hence some deduplication/sharing strategy is needed.
