      `conforms_to` records what the sources say, in their words. This records which
      standard that is. Populate both for the same standard: one is verbatim evidence,
      the other is the normalized term, and they answer different questions.

      Use `OTHER` when the sources name a standard this vocabulary lacks, and keep
      the name in `conforms_to` so nothing is lost. Never pick a near-neighbour —
      reporting BIDS because a dataset is neuroimaging, when the sources say otherwise,
      is an invention.'
