"4.4. move" states
The target location MUST NOT be part of the location defined by
"from"; i.e., a location cannot be moved into one of its children.
This constraint is backwards. I.e. to disallow moving into a child,
{ "op": "move", "from": "/a/b/c", "path": "/a/b/c/d" }
this should read:
The "from" location MUST NOT be a proper prefix of the "path" location;
i.e., a location cannot be moved into one of its children.
I suggest using "proper prefix" instead of just "part of". For example,
"/a/b/c" is "part of" "q/a/b/c" but such a move should be allowed
because it is not a proper prefix.
As currently stated, moving a value UP would be disallowed. Below, the target location is part of the "from" :
{ "op": "move", "from": "/a/b/c/d", "path": "/a/b/c" }
