 %			\bleedcell[5mm 10mm]{..}
 %			...
 %		...semantics similar to CSS margins...
+%		not sure how to architect this yet:
+%			- should this trim the content?
+%			- should this take-up space? 
+%		an alternative way to think about this is to create a clip cell 
+%		that clips content to the given edges/margins, with an option 
+%		to align content to the parent cell or to the clip box...
+%		...this might even be an extension to the current cliptocell...
 % XXX ASAP should cover/jacket/endpaper/spread templates/cells account
 %		for \bindingoffset (likely no) and/or \gutteroffset ???
 %		...especially relevant to endpaper/spread...
