# glyph-data

# Glyph Data Character Being Referenced

An `IDREF`-type attribute that points to the @id attribute of the <glyph-data> character inside a <private-char> element. The idea is to use the full <glyph-data> with its name and bitmap once, then point to an existing character instead of defining the entire <glyph-data> element repeatedly.

## Remarks

Once a private character has been declared using a <glyph-data> element, the character can be reused by using this attribute on a <glyph-ref> element to point to the existing full <glyph-data> element (bitmap included).

## Attribute Values

#### In Element

##### <glyph-ref>

Value | Meaning
--- | ---
An identifier (IDREF) | 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.
Restriction: This attribute may be specified if the element is used.
