<num> ISO Numeric Emphasis
A number appearing in running prose. The <num> element is provided to allow numbers to be tagged so that the decimal separators and group separators appearing in them can be identified explicitly; this is helpful when the document is to be rendered in a style which may require different decimal or group separators in different contexts or for different languages.
It is not required for all numbers that appear in the text to be tagged using <num>. This is a processing convenience. In some environments, the choice of decimal and group separators is fixed for all documents; in others, there is no requirement that the separators be explicitly identified. Even in environments where the <num> element is used, numerals which are rendered without either a decimal or a group separator may typically remain untagged.
