Full description or summary of the content of a graphical object, table, or textual object such as a text box. The long description is used by some systems to make the object accessible to people or systems that cannot read/see/display the object.
Conversion Note: This element is not to be used as a replacement for <caption>, which is a visual element displayed as part of a figure, table, etc. The <long-desc> is not a visual element, rather, it is used to be spoken in circumstances where the graphical element cannot be viewed. This element differs from the <alt-text> element which contains text that is displayed when the figure, caption, or other major element is not available or cannot be processed by the person or device type being addressed.
