As I said, those latter two tags would only appear on cemeteries that 
can be seen from the water and can be used as navigational markers. We 
need these differentiated tags for the various marine navigation 
specific renderers & other applications.

It is the second two tags that should be considered for deprecation, as 
they belong an abandoned tagging proposal.

We do not ask that our tags be applied by the wider mapping community, 
only that where they are found, not to delete them!
