Note that I spoke about XHTML 1.1. Some think that 'text/html' should 
be officially permitted for XHTML 1.1. When it comes to those pages you 
mentioned, then is labeled as 'XHTML 1.0'
           is labeled as 'XHTML 1.0'
     is labeled as 'XHTML 1.0' is labeled as 'XHTML 1.0'

And all are served as 'text/html', which is permitted, according to the 
current MIME registration for 'text/html'. So no need, according to 
official standards and registrations, to give the impression that the 
very DOCTYPE makes them invalid.

And the average Web author also think that JavaScript is related to 
Java, doesn't he? Judging from all the JavaScript tutorials which tells 
us that it does not, one should think that this was a huge problem ...

It *might* serve point to mark 'XHTML 1.1.' pages as having an error if 
served as 'text/html'. The question is *which* point it serves.
