No way to register `VertexOutputScheme` if not using any of the basic outputschemes?

[EricMEsch]

I think the only place where the VertexOutputScheme is in RMGHardware.cc:

  // also store primary vertex data, if we have any other output.
  if (!fActiveOutputSchemes.empty()) {
    fActiveOutputSchemes.emplace_back(std::make_shared<RMGVertexOutputScheme>());
  }

But this happens before any optional outputscheme and any user-provided output schemes are registered.

Am i correct, that the only way to get the VertexOutputscheme is to register any volume either as germanium, scintillator or optical?

yes, currently it is like that.
