[Seaside] XHTML

Given that there's been ongoing discussion (both on and off list) about 
Seaside's XHTML compliance, I thought the below was interesting.  It's 
from the WHATWG mailing list (see http://www.whatwg.org).  Dave Hyatt 
is the development lead on Safari.

Has anyone noticed this affecting anything in practice?  Are we better 
to output HTML4 Transitional for now, and flip the XHTML switch once 
browser support improves?
