Query: Priority and correctness on "From Schoenberg to Pick-Nevanlinna: Toward
  a complete picture of the variogram class" by Porcu and Schilling (2011,
  arXiv:0812.2936)   It is not the purpose of this correspondence to complain about that six out
of seven theorems listed in Porcu and Schilling (arXiv:0812.2936; 2011,
Bernoulli) belong to others, but not to the authors themselves. This is simply
a call for the priority, originality, and correctness.
