Missing Textual Content
Experience teaches that feeds which contain textual content are in general more useful than those which do not. Some applications (one example is full-text indexers) require a minimum amount of text or (X)HTML to function reliably and predictably. Feed producers should be aware of these issues. It is advisable that each atom:entry element contain a non-empty atom:title element, a non-empty atom: content element when that element is present, and a non-empty atom: summary element when the entry contains no atom:content element. However, the absence of atom:summary is not an error.
No action is required as Atom processors MUST NOT fail to function correctly as a consequence of such an absence. However, consider ensuring that there is at least a human readable summary or content for each entry.
