It seems I may have caused some confusion. I understand that LONGDESC is implemented in IE5, so you could look at it there. I imagine it could also be implemented by a browser like Lynx in the same way that it provides optional links to images themselves. Blynx and Tiny are two browsers which provide an accesskey mechanism, although it is not author-specified but auto-generated.

I was talking about elements / attributes that are in HTML 4.0, in particular Longdesc, Accesskey and Header + ID. Now I'm confused about whether or not is known how Longdesc is to be used: Wendy says it is not known and the UA group are looking into it, and Charles says it is known! If it is known, I think 2.7 of the Techniques could briefly describe, for example, how a screen reader might inform a user of the presence of the link, and whether this would differ for images, scripts or applets. If it is not yet known the Techniques could say that this is under discussion and describe how it is expected to be used. Regarding Accesskey: from previous discussions it seems that this is currently supported more widely (by mobile devices, I think). It would also be useful to have a brief description of how a screen reader might inform a user of the presence of Accesskeys, and how the user might interact with them. I assume the interaction with Accesskey depends on which element it is used with. Regarding Header & ID for Tables: I don't know whether these are currently supported by any type of device. If they are not, is it known how they are likely to be used? As I have suggested above the Techniques could have either a description of how they are used, or are likely to be used. I think all this would help authors in both how such elements should be implemented, and understanding how users of different browsers and assistive technology interact with elements.
