This element indicates that content is an Acronym (an abbreviation
formed from the initial letters or groups of letters of words in a
phrase.) Acronyms are used extensively in Western languages, as well
as languages such as Chinese and Japanese. The TITLE attribute is
suggested for providing the full or expanded form of the acronym.
While knowing the expanded form may not be implicitly important in
the rendering of the content, it can assist in speech synthesis,
spell-checking, and other document management scenarios.
Some acronyms can have unexpected pronunciations, such as being
pronounced as a word rather than letter-by-letter. Style sheet
properties should be used in such cases to aid in the
pronunciation of the abbreviated form.
Internet Explorer 4.0 does not add any special rendering to the
contents of this element, but common attributes that are applied
are understood.
Netscape 6.1 applies an underline effect to this element along with a
special mouse cursor when hovering (an arrow with a question mark.)
Later versions apply only a dotted underline effect.
Opera 7+ applies a dotted underline effect to this element; in previous
versions no special extra formatting was applied.
