Firefox and Chrome are implementations of the WHATWG HTML 5 standard. 
The first three letters stand for Web HTML Applications.  That means 
they are not primarily designed for documents, but rather for programs 
that run in the browsers.  As such, they implement the language designed 
for that, including all its scripting features.

Lynx was designed for documents, in the W3C's versions of HTML. 
Tolerance of the WHATWG standard is just bolted on.

I don't think that WHATWG were really interested in XML versions.  They 
are not really into formal syntaxes.  One consequence of this is that 
there is no DTD.  As such, I'm not sure how you can really claim to have 
validated HTML5 as XML, for more than well formedness.

It seems to me that anyone serving HTML5 as XML is really making some 
sort of political point, but found it strange that the document in 
question denied its markup language origins by being all on one line 
with no optional spaces.
