But is that an RA constant, or something under the covers? ie. does that
need to be in svn_ra.h for client consumption, or can RA determine that
privately and compensate?

For example, ra_dav can do everything but the symlink operations and
rotate(). Those will need to query the server to determine whether to use
new/old marshalling. But to the svn_ra user, it is always available.

For ra_local, it is always available at both internal/client levels.
