For instance in the drag & drop section, include a recommendation on how to detect if the Web browser implements the key features (e.g. file drop). This is not trivial, and not standard yet. For instance, Firefox returns false to: { 'ondrop' in document.createElement('div') } although 'ondrop' is implemented.

I expect this to be fixed for Firefox 9 or 10. 55586 2 ian 2011-08-22 18:23:02 +0000 There's a "demos" field in the boxes where people can put demos showing how to do this. In general I'm reluctant to give an "official" way in the spec because each browser might have different subtleties, and the implemented reality and the specced convergence goal might not be quite in sync, etc. However, if anyone would like to offer a Web service that a script could ping and display information inline, I'd be happy to do that. That's what the status boxes do, for example: they ping a service which returns information about each section and then the boxes are generated from that. 57820 3 ian 2011-10-04 23:41:54 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
