Display attribute group
- @expanse
 - Determines
                     the horizontal placement of the element. Allowable values are: 
                     
- page
 - Places the element on the left page margin for left-to-right presentation, or right page margin for right-to-left presentation.
 - column
 - Aligns the element with the current column margin
 - textline
 - Aligns the element with the left (for left to right presentation) or right (for right to left presentation) margin of the current text line and takes indention into account.
 - spread
 - Indicates that, if possible, the object should be rendered across a multi-page spread. If the rendition target does not have anything corresponding to spreads then spread has the same meaning as "page".
 - -dita-use-conref-target
 - See Using the -dita-use-conref-target value for more information.
 
In DITA tables, in place of the @expanse attribute used by other DITA elements, the @pgwide attribute is used in order to conform to the OASIS Exchange Table Model. The @pgwide attribute has a similar semantic (1=page width; 0=resize to galley or column).
Some DITA processors or output formats might not be able to support all values.
 - @frame
 - Specifies
                     which portion of a border should surround the element. Allowable values are: 
                     
- top
 - Draw a line before the element
 - bottom
 - Draw a line after the element
 - topbot
 - Draw a line both before and after the element
 - all
 - Draw a box around the element
 - sides
 - Draw a line at each side of the element
 - none
 - Don't draw any lines around this element
 - -dita-use-conref-target
 - See Using the -dita-use-conref-target value for more information.
 
Some DITA processors or output formats might not be able to support all values.
 - @scale
 - Specifies a
                     percentage, selected from an enumerated list, that is used to resize fonts in relation
                     to the
                     normal text size. This attribute is primarily useful for print-oriented display.
                     
                     
The @scale attribute provides an acknowledged style-based property directly on DITA elements. For the <table> and <fig> elements, the intent of the property is to allow authors to adjust font sizes on the content of the containing element, primarily for print accommodation. An <image> in these contexts is to be scaled only by its own direct scale property. If not specifically scaled, such an <image> is unchanged by the scale property of its parent <table> or <fig>.
Allowable values are 50, 60, 70, 80, 90, 100, 110, 120, 140, 160, 180, 200, and -dita-use-conref-target. Some DITA processors or output formats might not be able to support all values.
