Notably it was felt in the GNAF implementation that there was a need for some form of code list to facilitate the discovery of meaning - I believe this view was also shared by @andrea-perego
Currently there is no detailed discussion of a code list approach in the best practices. This could be an enhancement needed to facilitate implementation.
Updated OS Names API implementation report could provide one example of partial conformance to BP 14 (now BP 15), but it doesn't use a code lists approach
So far none of the implementation reports (GNAF, NRW, PDOK) implement BP 14: Describe the positional accuracy of spatial data.
