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.
Usage: 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.
