Abbreviation (NISO JATS table model)
An abbreviated version of the cell’s content. This allows visual browsers to use the short form if space is limited, and non-visual
browsers can give a cell’s header information in an abbreviated form before rendering each cell. (This attribute is based
on and intended to be converted easily to the XHMTL abbr attribute.)
|Text, numbers, or special characters
||A brief note of what is in the cell, mostly for use by accessibility software.
|Restriction: @abbr is an optional attribute; there is no default.
