(sorry if this is obvious, haven't been following) To answer this question specifically. The last CSSOM draft defined almost nothing in detail. Especially when it comes to string representation of CSS constructs. All it said about CSSUnknownRule was "The CSSUnknownRule interface represents an at-rule not supported by this user agent." Considering that the CSS parsing specification dicates throwing away everything you do not recognize without defining implementation details as to what should be thrown away etc. this is highly unuseful. You mention preserving unrecognized properties as well and presumably other constructs than unrecognized at-rules too? It's not all clear to me how all that could work nicely, but maybe you can convince an implementor to put some thought into it. Personally I hope XBL will be able to solve the primary use case you mention. I.e. providing a shorthand (a binding in the case of XBL) for custom implemented look and feel. -- Anne van Kesteren http://annevankesteren.nl/
