Local Attributes (defined for this element alone)
Attribute: orient (Orientation)
Description
This attribute, if used, specifies that the figure should be displayed in "port"rait or "land"scape. When set to the landscape option, this is a good indication that the figure is wide, and may need to be treated in a special way even in non-page media. Although "port" is not an explicit default value, it should be treated as the assumed default value when this attribute is not present.
Specification
This attribute is not required. The allowed values are "port" and "land".
DTD Definition
                orient                   (port | land)  #IMPLIED 
.
Attribute: pgwide (Page Wide)
Description
This attribute indicates that the figure must occupy the full width of the page when set to "yes". Although there is no explicit default value, the alternative setting of "no" should be assumed to be the default option that applies when the attribute is not present.
If the orient attribute is also present, the width is determined by the orientation, so the width of the page can be interpreted as the portrait width or the landscape width as appropriate.
Specification
This attribute is not required. The allowed values are "yes" and "no".
