Hi Daniel Thanks for the reply, and pointing out what the guidelines say. I must admit that I think the guidelines are wrong :-( Forcing all automatically generated ALT information to contain a null string means that nobody is provided with information which can be useful in circumstances. To be it seems intuitively wrong for an authoring / conversion tool to throw away resource metadata. I would argue it would be better for the information to be provided and then filtered out if necessary. I'd also argue that the guidelines should at least say that authoring tools should provide options for creating null or automatically generated ALT text, so that an organisation has some choice in this matter (e.g. the BBC might choice to provide this information as they have their Betsie tool for stripping out information).
