Indeed.  I was using an older version of lynx.  It seems 
v2-9-0dev_0l regressed in dropping application/xhtml+xml from 
Accept.  That’s a consequence of:

        --- a/src/HTInit.c
        +++ b/src/HTInit.c
        @@ -179,6 +179,7 @@ void HTFormatInit(void)

             SET_INTERNL("application/xhtml+xml", "www/present", HTMLPresent, 
1.0);
        +    SET_INTERNL("application/xhtml+xml", "www/source", HTPlainPresent, 
1.0);
             SET_INTERNL("text/css", "www/present", HTPlainPresent, 1.0);
             SET_INTERNL(STR_HTML, "www/present", HTMLPresent, 1.0);
             SET_INTERNL(STR_PLAINTEXT, "www/present", HTPlainPresent, 1.0);

I can’t say I fully understand what happens; I haven’t looked too 
deep into it.

I don’t buy this.  What is and isn’t XHTML isn’t dependent on what 
the client declares it can handle.  Please help me understand why 
you think that, with a citation perhaps.
