The "rel" attribute in HTML specifies the relationship between the current page and the linked page. The "bookmark" value for the "rel" attribute specifies that the linked page should be considered a permanent bookmark-style link, which is useful for creating a table of contents for the document. When used in a hyperlink, it indicates that the target URL represents a bookmark-style link, i.e., a link to a specific, named location within a document. The user's web browser or other software can use this information to provide users with convenient ways to access frequently used locations within the document, such as through a menu or list of bookmarks.
