The HTML5 <cite> tag is necessary when indicating the title of a specific work that is incorporated in the HTML document. It is useful when putting the title of a book, song, movie, TV show, painting, sculpture and other works.
It has to be emphasized that putting the name of the person responsible for the work should not be included because this is not part of the title anymore.
Using the <cite> tag is just the same for both HTML5 and HTML4.01. It is also supported by the major web browsers like Safari, Google Chrome, Internet Explorer and Opera.
When it comes to Global Attributes and Event Attributes, the HTML5 <cite> tag is capable of supporting both.
