<xmp>The PRE element tells visual user agents that the enclosed text is "preformatted". When handling preformatted text, visual user agents:
May leave white space intact.
May render text with a fixed-pitch font.
May disable automatic word wrap.
Must not disable bidirectional processing.
Non-visual user agents are not required to respect extra white space in the content of a PRE element.
The DTD fragment above indicates which elements may not appear within a PRE declaration. This is the same as in HTML 3.2, and is intended to preserve constant line spacing and column alignment for text rendered in a fixed pitch font. Authors are discouraged from altering this behavior through style sheets.
