  # Bump it when a version is issued, in step with owl:versionIRI.

  # Once a version is published by OMG, its OMG document number is

  # beta 1 is ptc/25-02-01, hence February 2025 in the frozen archive. The
  # value below is for the working draft, which has no OMG document number
  # yet, so it tracks owl:versionIRI instead.
