Some applications (one example is full-text indexers) require a minimum amount of text or (X)HTML to function reliably and predictably. For that reason, it is advisable that each atom:entry element contain a non-empty atom:title element, a non-empty atom:summary element when the entry contains no atom:content element, and a non-empty atom:content element when that element is present.
I find the conflation of presence and emptiness a little opaque. I'd rather the text said that, in general, when any of these elements are present they shouldn't be empty. The other part of this text, that summary be present when content isn't, can then be separated out for the sake of clarity.
Otherwise, it's fine.
