WARNING

It is possible—indeed, in some senses, it is the point of this test page—that IE/Win may crash or act in peculiar ways on this page.

This is a div with an id that has a value of tags. It may cause conflicts with IE/Win's document.tags.

The following problems are known in IE/Win:

Printing the page may cause a script error in one of the system DLLs, leading to a crash of the browser.
Any attempt to reference document.all.tags via scripting in IE/Win will return an object corresponding to the ID'ed element. This could cause severe problems for scripts that rely on document.all.tags method that usually exists.

JS test-- fails if the result is '[object]'.
