The SVGAltGlyphElement interface represents an <altglyph> element. This interface makes it possible to implement more sophisticated and particular glyph characters. For some textal representations as: ligatures (e.g. æ, ß, etc ), special-purpose fonts (e.g. musical symbols) or even alternate glyphs such as Asian text strings it is required that a different set of glyphs be used than the normal given character data.


This interface also inherits properties from its parent interface, SVGGraphicsElement.

It corresponds to the attribute glyphRef on the given element. It's data type is 'String'. It defines the glyph identifier, whose format is dependent on the ‘format’ of the given font.
It corresponds to the attribute  format on the given element. It's data type is 'String'. This property specifies the format of the given font.
