VML (Vector Markup Language) is an XML language used to produce vector graphics. VML was submitted as a proposed standard to the W3C in 1998 by Microsoft, Macromedia, and others. VML was rejected as a web standard because Adobe, Sun, and others submitted a competing proposal known as PGML. The two standards were joined and improved upon to create SVG.
Even though rejected as a standard by the W3C, and typically ignored by developers, Microsoft still implemented VML into Microsoft Internet Explorer 5.0 and higher and in Microsoft Office 2000 and higher.
