4.12.6 TITLE attribute

This attribute is optional, and is informational only. If present its arguement should be the TITLE of the document whose address is given by the HREF attribute. This may be useful for the following:

• The browser may display the title of the document prior to retrieving it. For example the browser could display the titles as a margin note or in a small box while the mouse is over the anchor.
• Some documents -- mainly non-HTML documents such as graphics, plain text and Gopher menus, do not come with a title themselves. Therefore putting a title in the link is a way to give them a meaningful label.
