Decommissioned tutorials

The tutorials "An Introduction to Multilingual Web Addresses" and "Using language information in XHTML, HTML and CSS" have been decommissioned, to facilitate updating of material and reduce duplication.

The information in the first tutorial is already covered by the more up-to-date article An Introduction to Multilingual Web Addresses. The meat of the second tutorial is covered by the articles Styling using the lang attribute, and Setting language preferences in a browser.
