category – set |category=no if, and only if, a banner is being used for demonstration or testing purposes, to prevent unnecessary or undesirable categorization. Otherwise, omit this parameter.
importance – valid values are: top, high, mid, low, na (case-insensitive).See the importance scale for details. Setting an explicit value of NA is rarely necessary; for this, either leave |importance= blank or omit the parameter.
attention – set |attention=yes if the article needs immediate attention from experienced editors. Use only if another parameter does not cover the need for attention; this should be used sparingly. It is strongly encouraged to also add a section to the talk page explaining what needs attention.
needs-infobox – set |needs-infobox=yes if the article needs an infobox. Remember that infoboxes are not suitable for all articles, and can overwhelm short articles.
