Changes
Change after update, per volume=_is_a_Roman_Numeral|this discussion. I think I got this description correct.
* <b id="csdoc_volume">volume</b>: For one publication published in several volumes. Displays after the '''title''' and '''series''' fields; {{#if:{{{magazine|}}}|prefixed with 'Vol. '.|volume numbers should be entered just as a numeral (e.g. 37); volume values that are wholly digits, wholly uppercase roman numerals, or less than five characters will appear in bold. Any non-numeric value of five or more characters will be presumed to follow some other convention and will not appear in bold.}}
