VML, the Vector Markup Language, is a vector image format that is represented by XML. It has been deprecated since SVG was accepted by the W3C, and should be used only for compatibility.
VML, the Vector Markup Language, is a vector image format that is represented by XML. It is a competing standard to SVG, as VML was never formally accepted by the W3C. VML has not been updated significantly since 1998, when it was submitted, and is considered deprecated in favor of SVG.
VML is used for websites wishing to display vector graphics for old releases of Internet Explorer, since IE has generally poor SVG support. IE9 rectifies this partially, but still only adequate support. Very few other browsers have support for VML.
VML has also been used by Microsoft Office since 2000, and continues to be used as the suite's main vector image format. OpenOffice holds deprecated support for VML for this reason.
