As we have already two engines not supporting such models, let's proceed with treating non-morphed primitives as having zero morph targets (and asserting all conformance implications of that).

Yes, the extension specs need to be upgraded: - to the new JSON schema version; - to use BCP 14 normative language; - to use AsciiDoc tooling (long-term).

For now, I'd say that extension schema files are "located" in the same folder as the core schema files for the purposes of reference resolution. Long-term, we should plan for...

The JSON-Schema `$id` property is semantically close to XML namespaces and JSON-LD contexts. It does not require any network operations on its own.

@emackey Direct quotes from the JSON-Schema spec: >The `"$id"` keyword identifies a schema resource with its canonical URI. > >Note that this URI is an identifier and not necessarily a...

Yes. Added to `2.0.x` milestone to keep it around.
