XML, the extensible markup language, is a quickly evolving technology that presents a viable alternative to courseware products and promises to ease the burden of Web authors, who edit their course pages directly. XML uses tags to label kinds of contents, rather than format information. The use of XML enables faculty to focus on providing contents, leaving the task of rendering contents to experts, who provide a single stylesheet used for formatting purposes. This stylesheet has to be edited once, saving time and effort and ensuring consistent appearance of course pages that reference it.
