Then question remains: how _should_ a site handle the situation where 
it's got an image element, a URI to show in it, and alternate text?

In particular, how should it handle this situation if it wants to have a 
basic library for doing various DOM manipulations so the various people 
doing the authoring don't have to reinvent the wheel all the time and if 
it has pages in both XHTML1 and XHTML2?

While true, it's possible to create an XHTML1-conformant image that 
serializes as text/html, while it's impossible to do so for an 
XHTML2-conformant image.

I don't see how it's a red herring to point out specific issues that are 
conflicting.

Please indicate to me how the document could possibly be made conforming 
here if all you have are the HTMLImageElement, the URI to show, and the 
alt text for the image.

See above.  The naming conflict means that it's impossible to author 
conformant content in some situations.

Again.  You have an HTMLImageElement, a URI, and some text that is 
alternate text for the image.  How do you put those together in a 
conforming way?
