In the general case? There is a small literature on this in the
functional world. E.g.:

 (Pictures, 1995)
http://www.ecs.soton.ac.uk/%7Eph/papers/funcgeo2.pdf (Functional Geometry, 2002)

I don't recall any papers specifically addressing equality. The main
concern in my reading has been expressing constraints in the layout
(e.g. this box is twice as wide as the elements it contains).
