Some applications may choose to require a minimum amount of inline text or (X)HTML data to function reliably and predictably. For that reason, atom:entry elements are advised to 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.
We observe that the paragraph above is getting support from the WG members who have been most engaged in this area of the discussion.
Rephrasing slightly because I don't believe that XML elements are very responsive to advice. As an example freak, I'd also like to keep the concrete example of a full-text indexer from the consensus call. Thus,

Paul and I consider that the following text has consensus support of the WG and the editors are directed to include it in the format draft (editorial judgment call on where to insert):
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.
