Using slapo-rwm to change attribute

Hi!

I have an application that uses the 'c' attribute to store a string describing a country name. The syntax of 'c' only allows a two-letter country code, but the application uses full country names. Therefore the attribute it *should* be using is 'co', or 'friendlyCountryName'. Unfortunately I cannot change this application. (It's Mozilla).

I have tried using the rwm overlay to map 'c' onto 'co', which works, but then the syntax of 'c' is still enforced.

I can, of course, change the schema definition of 'c' to that of 'co', but that seems bad practice. I could also disable schema schecking, but that is even worse. Are there better ways to work around this?

Thanks a lot,

Roel
