It's a non-standard, proprietary, presentational element.  Remove it. 
HTML is designed to markup the structure and semantics of a document, 
not its presentation.  CSS should be used for presentation instead.

Although there is not yet a standardised way to achieve that affect with 
CSS, there are some plans for various marquee related CSS properties in 
a CSS draft.  However, you must consider the accessibility issues of 
moving content.  Some users may find it irritating and/or impossible to 
read moving text.
