Value:

  VTKM_STATIC_ASSERT_MSG(::vtkm::cont::arg::internal::ControlSignatureTagCheck<tag>::Valid, \
                         "Provided a type that is not a valid ControlSignature tag.")

Checks that the argument is a proper tag for an ControlSignature.

This is a handy concept check when modifying tags or dispatching to make sure that a template argument is actually an ControlSignature tag. (You can get weird errors elsewhere in the code when a mistake is made.)
