The SVGAltGlyphElement.format property is a DOMString that defines the format of the given font. It has the same meaning as the 'format' property of SVGGlyphRefElement property. If the font is in one of the formats listed in CSS2([CSS2], section15.3.5), then its value is the corresponding <string> parameter of the font.
