Greetings Phokham,

Thanks for notifying us about your work with the framework.  We  
appreciate your input about the framework and how we can improve it to  
suite your needs.

Thanks.  That would be appreciated it.

We do need to document isValidUse more and clarify its use.  However,  
can you clarify your need to override isValidUse so it would return  
true all the time?

I believe that the default implementation is applicable to most cases,  
only IGJ overrides legitimately in our checkers.  Furthermore, the  
default implementation revealed some bugs in the Interning checker in  
the past.

I do not know much about ownership, but I can imagine having some  
invalid types: private inner classes can only be owned by enclosing  
class and not universe, so a use of '@OwnedBy(UNIVERSE) InnerClass' is  
not a valid use.  I am not quite sure if this makes sense in Universal  
Type System.

Mahmood
