Vector Markup Language (VML) is a deprecated XML language used to produce vector graphics. VML was submitted as a proposed standard to the W3C in 1998 by Autodesk, Hewlett-Packard, Macromedia, Microsoft, and Visio. Around the same time other competing W3C submissions were received in the area of web vector graphics, such as PGML from Adobe Systems, Sun Microsystems, and others. As a result of these submissions, a new W3C working group was created, which produced Scalable Vector Graphics (SVG). SVG became a W3C Recommendation in 2001 as a language for describing two-dimensional vector and mixed vector/raster graphics in XML. VML has been largely deprecated in favor of other formats, such as SVG. SVG is not compatible with VML. (Excerpt from Wikipedia article: VML)
