Note for Illustrator Users: In non-adjustable SVGs, all visible content is perfectly clipped to the new frame using an SVG construct that happens to be mishandled by Illustrator versions 10 and CS. These versions will reverse the Y-axis upon import. Versions CS2+ won't do this, but it has another problem in that objects only partially outside the clipping region are discarded. So for now at least, clipping regions can't be used in Illustrator documents intended for SVG roundtripping. When Walls creates a non-adjustable SVG, a clipping region is defined with a nested <svg> element. If you still want to bring the file into Illustrator a final time, say for printing, first use a text editor to remove the nesting. This is easily done by deleting two lines that are identified by comments in the SVG file.
