Query: Fragmentation Functions for Light Charged Hadrons with Complete Quark
  Flavour Separation   We present new sets of next-to-leading order fragmentation functions
describing the production of charged pions, kaons and protons from the gluon
and from each of the quarks, obtained by fitting to all relevant data sets from
e+ e- annihilation. The individual light quark flavour fragmentation functions
are obtained phenomenologically for the first time by including in the data the
light quark tagging probabilities obtained by the OPAL Collaboration.
