[castor-user] How to use a binding-file to solve name collision?

[h z]

hi, all
When I build java classes based on existing xsd files, there are always cyclic inheritence problems. I know this is because both elements and complextype with the same name. Using castor binding-file is a solution for this problem, but I donot know how to use it.
Anybody can give me an example?
Many thanks
