7.4.3 The title attribute
title = text [CS]
This attribute offers advisory information about the element for which it is set.
Unlike the TITLE element, which provides information about an entire document and may only appear once, the title attribute may annotate any number of elements. Please consult an element’s definition to verify that it supports this attribute.
Values of the title attribute may be rendered by user agents in a variety of ways. For instance, visual browsers frequently display the title as a “tool tip” (a short message that appears when the pointing device pauses over an object). Audio user agents may speak the title information in a similar context. For example, setting the attribute on a link allows user agents (visual and non-visual) to tell users about the nature of the linked resource:
Here’s a photo of
<A href=”http://someplace.com/neatstuff.gif” title=”Me scuba diving”>

…some more text…
The title attribute has an additional role when used with the LINK element to designate an external style sheet. Please consult the section on links and style sheets for details.
Note. To improve the quality of speech synthesis for cases handled poorly by standard techniques, future versions of HTML may include an attribute for encoding phonemic and prosodic information.
