Define a standard for helper parts

[Roland Melkert]

I have updated the draft at:

I'm still ok with my previous thoughts (#2 proposals in Willy's draft).

Except maybe the description one as noted by Milan Vančura here:

And a small correction on "The type or "qualifier" should be put here, e.g. "3D arrow", "2D arrow", "Arrow" (can be together with 2D arrow)"
I'm not sure it is clear I meant you can have the specific "3D arrow" or "2D arrow" keyword together with the general "Arrow" keyword.

Travis / Chris any thoughts?
