//back/sec[@sec-type = "long-descriptions"]
Give this section a sec-type attribute with value

and a title Text alternatives to non-text
content
.
Capture each long description in a child sec element with a
sec-type attribute with value long-description-object
.
Give this section a title as supplied. If a title is not supplied, use text that
identifies what media is being described, e.g. Text alternative to Figure 19.
.
Use one or more p element for the textual part of a long description. Complex images may require long descriptions divided into headed fragments, in which case use two or more sec elements and provide a title for each section.

<p>The male peacock head is metallic blue on the crown, the feathers of the head
being short and curled. The fan-shaped crest on the head is made of feathers
with bare black shafts and tipped with blush-green webbing. A white stripe above
the eye and a crescent shaped white patch below the eye are formed by bare white
skin. The sides of the head have iridescent greenish blue feathers. The back has
scaly bronze-green feathers with black and copper markings.</p>
