You mean, other than the one provided for passing an additional

Well, the intrinsic constraints are hidden because they're not supposed  
to be tampered with. When calling calibrate(), you can add an  
additional constraint; multiple constraints can be collapsed into one  
by using CompositeConstraint.

No, it's not trash---but you can do it already.
