can an extension override attributes?

I'm working with an base complexType and some other complexTypes that extend from it. I want to include an attribute ("name") in the base type, but the one snag is that one of the types extending from base type requires a name attribute that is less than 32 chars in length, and all the other types need a length of 100. So, can i define the attribute in the one exception type and expect it to override the attribute defined in the base type? thanks for the help. please let me know if this needs any clarification.
