E&W isn't versioned up to 2.5, so I couldn't redistribute your by-sa 2.5
work under an E&W license.  You may have been looking at
http://creativecommons.org/licenses/by-sa/2.0/uk/legalcode

See under 2.3 "any other Creative Commons licence with the same Licence
Elements."

I believe that is intended to cover "any equivalent international
license."  Other licenses include the more explicit language of the
generic version, e.g., 4(b) of
http://creativecommons.org/licenses/by-sa/2.5/nl/legalcode

However, IANAL.
