def parse( chunks )
  ## todo/fix: (re)use nameparser - for now "simple" inline version
  ##  fix!!! - note: for now lang gets ignored
  ##  fix: add hanlde
  ##  Leuven[nl]|Louvain[fr] Löwen[de]
  ##  Antwerpen[nl]|Anvers[fr] [Antwerp]
  ##  Brussel[nl]•Bruxelles[fr]   -> official bi-lingual name
  ##  etc.

  ## values - split into names (name n lang pairs)
  ## note: assumes (default) lang from more_attribs unless otherwise marked e.g. [] assume en etc.

  ## split chunks into values
