You really should look at the schema.org stuff and the SML WG. It already has a long list of complex objects you send in mail messages to allow people to collaborate in various ways. The code to use them is invariably written in Javascript, typically loaded from a file on a server and run in the browser, because these days that's how people write everything. Given the rule of thumb that our standards are most successful when they formalize existing practice, it seems like the right place to start. R's, John
