What I should have done, is had declarative look for a decorator 
@mapperproperty.  Which is identical to @classproperty, except its the specific 
decorator that declarative will actually look at.   I have already hit this 
glitch in my own code where I am using @classproperty for other reasons.

Class-level decorators are going to be more prominent in 0.7 so I will be 
getting this story straight.
