... not ideal. I don't know how many people use individual
stylesheets directly, but I suspect it's quite a few.

Hi,

I'd suggest keeping the change, creating different XSL files, and providing the wrapper stylesheets in files with the same names the real ones used to have. This way, it would be backwards compatible and the problem would be fixed.
