<endflag>The <endflag> element takes an optional image reference and an
optional <alt-text> element for identifying the end of flagged content. If
an image is specified, the specified image will be used to flag the end of the content, with the
<alt-text> contents as alternative text. If
<alt-text> is specified without an image, that text will be used to flag
the content instead of an image. If no image and no <alt-text> are
specified, then this element has no defined purpose. The <endflag> element
is allowed inside either <prop> or
<revprop>.
