77// If excerpts are not requested, the full content will go inside the description element.

79// Why are we not returning both excerpts and content by default?
80// Mainly for backward compatibility.
81// Excerpts should appear in the feed item's description element. Previous versions
82// of Full-Text RSS did not return excerpts, so the description element was always
83// used for the full content (as recommended by the RSS advisory). When returning both,
84// we need somewhere else to place the content (content:encoded).
85// Having both enabled should not create any problems for news readers, but it may create
86// problems for developers upgrading from one of our earlier versions who may now find
87// their applications are returning excerpts instead of the full content they were
88// expecting. To avoid such surprises for users who are upgrading Full-Text RSS,
89// excerpts must be explicitly requested in the querystring by default.
90//
91// Why not use a different element name for excerpts?
92// According to the RSS advisory:
93// "Publishers who employ summaries should store the summary in description and
94// the full content in content:encoded, ordering description first within the item.
95// On items with no summary, the full content should be stored in description."
96// See: http://www.rssboard.org/rss-profile#namespace-elements-content-encoded
97//
98// For more consistent element naming, we recommend new users set this option to true.
99// The full content can still be excluded via the querystring, but the element names
