- Profiles => similar to ARM (RVA or RVM ...)
- Platforms => the set of elements (interfaces, profiles, others?)
- Define via YAML
- Note: forces rewrite of this proposal: Introduction to spec
- TSC decision matches the proposal; henceforth, the term collections is no longer used, profiles are similar to ARM's profiles ('A', 'M', and so on), and platforms we'll defines, but basically the sum of all the elements that make up a usable system
