<extFigure>

<extFigure> (external figure) (in a writing system declaration) refers to a figure or illustration depicting the character form, which is stored in some declared notation external to the text.

Attributes

(In addition to global attributes)

`notation`	identifies the notation in which the figure is stored.
	Datatype: CDATA
	Values: a valid name associated with a given notation by means of a NOTATION declaration in the document type definition.
	Default: #REQUIRED
`entity`	gives the name of an external entity which contains the figure.
	Datatype: CDATA
	Values: a valid name associated with the external entity by means of an ENTITY declaration in the document type declaration .
	Default: #REQUIRED

Example

An image of the character form may be stored and transmitted in any desired graphics format. The declaration of the notation may specify a local system identifier for the processor (here it is imagined that we use a program called ‘pddraw.exe’ to process files in TIFF format), thus:

<!-- in the DTD: -->
 <!NOTATION TIFF SYSTEM 'pddraw.exe'>
 <!ENTITY lcthorn SYSTEM 'lcthorn.TIF' NDATA TIFF>
        <!-- in the WSD itself: -->
 <extFigure notation="TIFF" entity='lcthorn'/>

More usually, a PUBLIC identifier is associated with the notation:

<!-- in the DTD: -->
 <!NOTATION TIFF
            PUBLIC '-//XXX//NOTATION Tagged Image File Format//EN'>
 <!ENTITY lcthorn SYSTEM 'lcthorn.TIF' NDATA TIFF>
     <!-- in the WSD itself: -->
    <extFigure notation=TIFF entity='lcthorn'/>

Example

Character shapes may be conveniently conveyed in forms other than graphics images; one might, for example, define a character shape using a font-design program such as Donald Knuth's MetaFont program (which can be used to generate fonts for processing with TeX):

<!-- in the DTD: -->
 <!NOTATION metafont
            PUBLIC '-//DEK//NOTATION MetaFont//EN'>
 <!ENTITY lcthorn SYSTEM 'lcthorn.TIF' NDATA metafont>
        <!-- in the WSD itself: -->
 <extFigure notation='metafont' entity='lcthorn'/>
