I am sceptical about the idea of trying to make a "mainstream protocol", if only because "mainstream" means "simplified" which means "poor". I think we need an upgrade of Z39.50 for libraries, documentation, full-text retrieval, that kind of things. Let us stick to our business, and not try to conquer the whole world. Z39.50 was a tremendous success, and it will be hard to repeat that. So a new protocol should somehow be built upon Z39.50, as a Z39.50 Next Generation with backwards compatability. I see Z39.50 like MARC or ISO2709 or ASCII: You can't throw it away, at least not yet. Two more remarks: I would argue against hard-coding any external protocol (like XML) in the new protocol. I am a partisan of the Scan functionality, and I will defend it!!
