Windows Media metafiles are based on the XML syntax. They can also use the ANSI or the UNICODE (UTF-8) formats. They are made up of various elements and their associated tags and attributes. Each element in a Windows Media metafile defines a particular setting or an action in Windows Media Player. To work, some elements must be located in a specific position in the file relative to other elements. Some elements have mandatory tags and attributes that must be defined in the Windows Media metafile.
The Windows Media Player 9 Series SDK provides an overview and programming guide sections, and a full reference section on metafile element tags, their attributes and values, and special conditions related to each element.
