 * access-date: Full date when the content pointed to by url was last verified to support the text in the article; do not wikilink; requires url; use the same format as other access and archive dates in the citations. Not required for linked documents that do not change. For example, access-date is required for online sources, such as personal websites, that do not have a publication date; see WP:CITEWEB. Access dates are not required for links to published research papers or published books. Note that access-date is the date that the URL was found to be working and to support the text being cited.

 * archive-date: Archive-service snapshot-date; preceded in display by default text "archived from the original on". Use the same format as other access and archive dates in the citations.

 * – selects archive-url; used when url is still 'live' but no-longer supports the text in a Wikipedia article

PDF is auto-detected and should not be specified. Does not change the external link icon (except for PDF).

(This is not a concern with PDF, because the auto-detection will add "(PDF)" as descriptive text.)
