docs: 🏗️ add interface for an umbrella extensions class #156

The design of the toml file looks good and makes sense to me!
Where I’m struggling a bit is seeing how the Extension class matches / implements this design.
Based on the toml file, I would expect Config to have the fields version, strict, exclusions, and extensions, where an extension is either of type required or custom_check. So one Config can have multiple Extensions, but one Extension can only express one check (whether required or custom).
The design of the Extension class seems to allow multiple checks (whether required or custom) to be expressed in one Extension. Is this correct? Or can you explain the class structure a bit more?

@martonvago One config can only have one extension class. See the TOML spec for Array of Tables: https://toml.io/en/v1.0.0#array-of-tables. |

Do we want this to be a string and not a e.g. a float 2.0? At least, we should include the .0 since we know there's a v2.1 on the way.

We could provide a set list of potential values in it, like ["v2", "v2.0", "v1", "v2.1"] to allow short hands of v2.

That's true, but I still don't like the ambiguity of "v2" 🤔 Like would that refer to "v2.0" or "v2.1"?

Well, it's just that their documentation refers to v2: https://datapackage.org. The only place v2.0 is used is in the Changelog. But everywhere else, it is v2. I'd rather keep aligned with what they use in their language. But I'm also not super strongly opinionated on this.

@lwjohnst86 That's true; they tend to refer to v2 on their website. They do, however, use 2.0 in their profiles, e.g., https://datapackage.org/profiles/2.0/datapackage.json.

Ah okay, so [[extensions.required]] creates a structure like "extensions": {"required": [...], "custom_check": [...]} and not an array of extensions (like e.g. [[exclusions]]).
Okay, then I'm happy with this, I'd just prefer the singulars/plurals to be aligned with the structure. 👍 👍
