Most characters in an XML document can be expressed as regular Unicode codes. Characters not in the standard Unicode™ tables have traditionally been expressed as explicit font calls (non-portable), created as inline graphics, or defined in one of the Unicode™ private-use areas where users may define their own characters. This element is used when there is known to be no font available to render a private-use character. The <glyph-data> element provides information on the actual glyph that is associated with the private-use character.

Once a private character has been declared using a <glyph-data> element, the character need not be defined with the same <glyph-data> element every time it is used. The character can be reused by using the <glyph-ref> element to point to the full <glyph-data> element. The pointing uses the ID/IDREF mechanism, using the @glyph-data attribute of the <glyph-ref> element to point to the @id attribute of an existing <glyph-data> element. Since the reference uses the ID/IDREF, the reference may precede or follow the element to which it is pointing.
