Redefinition and derivation by list

Probably a weird question, but I haven't found anything in the rec nor 
in the schema for schema which would disallow using a derivation by list 
when redefining a simple type.

Since a derivation by list is changing the semantic of the simple type, 
I was wondering if this is really possible per the rec and if it is, 
what's the logic behind.

Thanks for your answers/comments!
