Um... That's strange, because I'm able to do that.
Maybe my description is not clear?

If I have the following schema setup
1. objectClassA with attribute1 inherits from top
2. objectClassB with attribute2 inherits from objectClassA
3. objectClassC with attribute3 inherits from objectClassB
then I can achieve multiple schema object class inheritance.

objectClassC will contains attribute1, attribute2 and attribute3.

objectClassA is my superior class who inherits from top.

Am I correct?

Thanks,

David Chu
