The basic mechanism is to define style info as production rules. The left hand side of the production operates on: a) attribute values and tag names b) the context in which some element appears c) other parameters such as the age of the document and the current window size d) available resources, e.g. font name/size. The right hand side of the production specifies: a) nodal properties such as font name/size for some element, plus color and margin indents b) spatial relationships like above, below, left-of, right-of The production is also associated with a weight following H&kon Lie's suggestion for cascading style sheets. I will be working with H&kon to refine this approach and implement it as part of the W3O testbed browser. We believe that it can be implemented efficiently and will lead to the ability to handle arbitrary SGML DTDs. ----- So there is plenty of evidence for prior art pertaining to CSS before the filing date of Microsoft's patent in July 1995.
