[Tobago] Is there a @parentId variable?

[Helmut Swaczinna]

Hi,

I know the @autoId variable which can be used to refrence the id of current 
component. A @parentId variable
would be useful to reference the id of the enclosing component. For example to 
be used in a f:validateLength or
f:validateLongRange tag. I want to read the contraints for the validate tags 
from a map in my backing bean with
the component id as the key.
