This patch revises part of the implementation in PR 417.
* `in-minListLength` was not added to the Core document, but it was
referenced in SHACL-SHACL. Verbiage is added to Core in line with the
text drafted for Issue 429.
* `xone-memberShape` was added as a reference in SHACL-SHACL, but
doesn't exist in the Core document. `xone-members-node` is the anchor
in the Core document. `xone-members-node` is now used.
* The `PropertyShape` for `sh:in` set a minimum required length of 1,
which after discussion in Issue 429 appears to be a backward-
incompatible change. A shape paralleling the original suggestion for
`sh:xone` is added to house that new restriction at the same warning-
level severity.
An implementation style point: The property shapes housing
`sh:minListLength` are given IRIs after sketching a test
(`.../in-003.ttl`) and assuming it would be more desirable to have an
IRI-identified shape in the results graph, rather than a blank node.
A testing style point: Rather than running SHACL-SHACL over the whole of
a test, shapes from SHACL-SHACL are copied into some focused tests
(`.../{in,xone}-003.ttl`).
