Message

This web application contains deprecated Vector Markup Language element [ELEMENT] (File: [FILE_NAME]).

Background

Since Windows Internet Explorer 11, Microsoft has deprecated support for Vector Markup Language (VML). This language was used to produce vector graphics displayed in web applications.

Note:Support for VML is available in Internet Explorer 11 in document modes 5, 7, 8, and 9; however, the performance is inferior to the standards-based replacements.

Resolution

The web application should be re-engineered by moving to standards-based technologies—for example, scalable vector graphics (SVG) format. Where this is not feasible, the Internet Explorer Compatibility View should be used. It can be triggered by using the meta attribute value X-UA-Compatible.
