Or does LaTeX interpret that in some other fascion? It is a very neat feature in fact: ihis means "this length is 1cm, but if you want to expand or shrink it to have a nice looking output, you can add up to 2mm or remove up to 3mm". For example, a medskip is elastic in this sense, and this is very important to give TeX some room to do proper typesetting. \hfill and vfill are special cases of that. OTOH, I guess that this is more important in a document class than directly in a document. So we should support that only if it does not clutter the interface too much. JMarc
