The service is intended to be used in the statement value formatter (see T187316). The service should generate the data to be presented, without any formatting, particular output format etc.
The outcome of this task will be a simple service, probably requiring the whole lexeme data to be available.
We expect the service to serve as the initial version of the service interface, that would allow to e.g. have presenting services operating on some DB indexes for performance, simplified presenting services to be used in tests, etc.
The initial interface will be of course subject to change as the work on T184997 progresses.
