34.2.3 Assigning
WAI image attributes with PI markers
You can use PI markers to provide text
equivalents of graphic images. The attribute value in the text of a marker
applies to the next anchored frame in a flow after the PI marker. Each
PI marker name must start with Graph and
end with the name of the attribute. Valid PI marker names are as follows
GraphAlt
|
Short
text equivalent of image; adds alt attribute.
|
GraphLongdesc
|
Path
to file with image description; adds longdesc attribute.
|
GraphTitle
|
Long
text description of image; adds title attribute.
|
For example, to provide an alt attribute
for each graphic, place a GraphAlt
PI marker just before the image.
