The most common link. Use this to turn a word or phrase into a link to another part of the document. linkend is the only attribute we use.

A link that refers to a document using it is URI. Use this for websites and ftp sites, but not for email addresses, which have their own specific tag. Please do not use this to link to other documents on the local system.

Marks a place in the document, which you can use to link to. Note that the id attribute on any other element where it is valid, will automatically generate an HTML anchor in generated HTML, so you do not need to duplicate these. Use anchors only when you need to jump into the middle of a longer page, for example, to a particular menu item, or to a particular option in a preference dialog.

A cross reference to another part of the document. Use this when you want to refer to the section without the name. This is one of very few unclosed elements allowed. linkend is the only attribute we currently use.

Use this to enclose an email address. Do not add “mailto:” to the email address, and do not use <ulink url=""> for email addresses. No attributes required.
