<LINK> - Document Relationships

This element defines relationships between this document and another file. The tag appears in the document head, not the body, and is not rendered as part of the page. <LINK> is also used to link auxilary files to the HTML document--external style sheets and scripts, for example. Some browsers, notably Mosaic, create tool bars based on the document's <LINK> elements. <LINK> can also be used to provide other versions in different formats, in different languages, or for different media.

It is illegal to close this tag. </LINK> does not exist.

Indicates an alternate version of the current document (such as in a different language or for a different medium).
Stylesheet
Indicates an external style sheet. Can be used with "alternate" for an "alternate stylesheet."
Script
Indicates an external script. Not all browsers support this; I know I have had trouble with MSIE, and had to resort to the <SCRIPT> element instead. (For those of you about to defend Microsoft's browser, I have version THREE! So don't explain that it works fine in 5.0 or whatever.)

You can also define your own link types by using a meta data profile. I have no idea what a profile is, so here the specification entry: HTML 4.0 - Meta Data Profiles It's in the section on the META tag, so there will be references to that tag and its attributes.
