What is it?
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.
