<desc>

A description is a statement that describes or contains additional information about an object.

The following list outlines common uses of the <desc> element:

<table> and <fig>
Provides more information than can be contained in the title
<xref> and <link>
Provides a description of the target
<object>
Provides alternate content to use when the context does not permit the object to be displayed

When used in conjunction with <fig> or <table> elements, processors SHOULD consider the content of <desc> elements to be part of the content flow.

When used in conjunction with <xref> or <link> elements, processors often render the content of <desc> elements as hover help or other forms of link preview.
