<url>
The <url> tag is used to link to an external website. If you are linking to a page within the same document, use <xref>
instead.
A <url> may be self-closing, but for accessibility reasons, it is recommended that the <url> wrap text that describes the link.
See An Accessible URL for an example.

for the web.
