In fact, this is what the not-yet-released Safari (that has switched 
over to libxml and SAX) does.  It will render up to the point of the 
first error, and then at the top of the page will show you a list of 
the errors while still rendering everything up to the first error 
below.  I plan to use libxml's push mode to enable incremental 
rendering of XHTML in Safari fairly soon.
