I like this idea, and it is something I've wanted to try out for awhile. I've been around since I we would set the font color on the body element, and nest tables for complex layouts. I've worked with SGML. I rode the XML is Everywhere wave of the late 90s. I've been dying to take web components for a spin for awhile. Particularly as we have a lot of XML, and a lot of XSLT's hanging around in feeding the content of our web application. I work in publishing content that is consumed by library patrons.
