Section 4.2 says:

The "remove" operation removes the value at the target location.

The target location MUST exist for the operation to be successful.

For example:

{ "op": "remove", "path": "/a/b/c" }

If removing an element from an array, any elements above the
specified index are shifted one position to the left.

It should say:

The "remove" operation removes the value at the target location.

The target location MUST exist for the operation to be successful.

For example:

{ "op": "remove", "path": "/a/b/c" }

If removing an element from an array, any elements above the
specified index are shifted one position to the left.

The target location MUST NOT be a reference to the root. It is an
error in this document:

{ "op": "remove", "path": "" }

Notes:

The semantics of { "op": "remove", "path": "" } are never specified. If we allow to remove the root element, what would the result be? It would no longer be a valid JSON document, hence I propose to explicitly require the path of the "remove" operation to not reference the root.

Mark Nottingham: This isn't an errata; it would require gaining consensus and updating the document. See also: https://github.com/json-patch/json-patch2
