<num> Number

<num> is a generic element used to encode any form of numeric information. It is only used when it is necessary to display a number in a special way or identify it as a type of number. Do not confuse it with other elements which may contain numeric information, such as <container>, <unitid>, or <eadid>. It may be used within <bibref>, <bibseries>, <entry>, <event>, <extref>, <extrefloc>, <item>, <label>, <materialspec>, <p>, <publicationstmt>, <ref>, <refloc>, <seriesstmt>, <subtitle>, <title>, <titlepage>, <titleproper>, and <unittitle>.

ALTRENDER – not required. Use if the content of the element should be displayed or printed differently than the rendering established in a style sheet for other occurrences of the element.
AUDIENCE – not required. Use to set whether the element’s contents will be visible to external users or to internal ones. Possible values are: “internal” and “external.”
ID – not required. Creates an ID for element. Can be used for linking.
ENCODINGANALOG – not required. May contain information to map this tag to other encoding schemas.
TYPE – not required. While this attribute is not required, it’s strongly advised that it should be used if the element is being used at all.
