I do think that an invitation to put all the features you would like to see but aren't XML Schema via the appinfo mechanism is an invitation for problems. The introduction of new "features" into XML Schema, in the hopes of such features making the next version, is asking for the browser wars revisited, and we are still smarting from that experiment. One of the reasons to have common specifications is to enable (not provide) interoperability. One of the major factors against interoperability is the use of custom slots/tags/whatever such as appinfo. I'm not against modularization, its just that appinfo doesn't provide a standard mechanism to create and document such modules. -Jonathan
