A couple more points.

1. I forgot to mention that the xml pragma throws IE Windows into Quirks mode.
2. By chance someone on another list posted an authoratitive piece on 
XHTML. It turns out that if you markup a page as XHTML and give it a 
.xhtml extension then Firefox will *not* render it if it has errors. 
I quote selectively:

Note, that this is only true if you name your file ,xhtml (which IE 
will, I think, refuse). If you name it .html FF will do it's best 
with the page.
