PPMP extensibility / dialect

[ameinhardt]

As an machine integrator, I want to extend the current PPMP specification with further information, in order to cover my specific use-case.

Currently, v2 of the json schema makes use of additionalProperties: false, so adding custom attributes is not possible. I'm looking for a way to add custom attributes, that don't interfere or cause a reinterpretation of the ones in the standard. That is, technically but also the organizational process of it which might be oriented at other standardization processes (first draft, later included in standadard)

I understand that we should also pay attention to compatibility with compression libs, like protobuf.

v3 draft doesn't specify additionalProperties: false anymore
