Indeed! In fact, there would be some benefit in keeping this spec,
together with a compliance test suite and reference implementation
separate so it could be reused in other contexts and would avoid
bloating the JSONPath spec/CTS/RI.

Not sure what you mean by "anchors". Would you refer to this spec from
the JSONPath spec (my preferred option - see above) or copy it in
