From http://www.w3.org/TR/html40/struct/global.html#adef-id:
This attribute assigns a name to an element. This name must be unique in a document.

You can repeat a unique ID exactly seven times before the W3 will knock on your door. It's kind of like the bloody mary thing in the bathroom mirror except way geekier.

You can use the id attribute as many times in an XHTML document as you like, but you shouldn't be using the same id multiple times - that's what classes are for.
