Is there a definitive ruling on what sources are legal for pulling monsters from for spells such as Planar Binding (or Simulacrum)? Unlike Summon Monster, there is not a creature list attached to the spell. Going through everything that comes up when searching planar binding, I see the occasional reference to players using the spell (even in the presence of PFS officials), but there's nothing about what they were allowed to use.
Are no monsters actually allowed to be called, Bestiary 1 monsters only, or all content from the Bestiaries?
