JSON-LD 1.1 issue with double-`@graph` expansion

json-ld-issue-graph-simplification.md

In Expansion step 20, expanded result maps that contain only a @graph entry are simplified:

If result is a map that contains only an @graph entry, set result that value.

In test t0081, I believe the expansion of the "input" key:

  "input": {
    "@graph": {
      "value": "x"
    }
  }

will be simplified by step 20.

Before step 20:

{
	"@graph": [
		{
			"http://example.org/value": [
				{
					"@value": "x"
				}
			]
		}
	]
}

After step 20:

[
	{
		"http://example.org/value": [
			{
				"@value": "x"
			}
		]
	}
]

However, the expected test output seems to assume that this simplification does not happen, and contains a double-nesting of @graph entries.

Understood, but it’s a big change coming late.

I think we can move the end steps to the API description, which has its own steps. All API methods that depend on expansion use the API expand() method entrypoint.
