Tough.  Than the "extended direct input" interface might need
a second submit button for "pretend that you saw text/xml" (?)

On the "extended direct input" page it wont't confuse users
who are not interested in such details.  This WAPFORUM XHTML
case could be documented on one of the two DOCTYPE FAQ-pages.

A pragmatic solution instead of a second button would be also
fine, e.g. with a message "assuming Content-type: text/xml" or
something in this direction:

Yes.  It's "direct input", experimental, and unrelated to all 
"valid whatever" icons.

When I was once lost with DOCTYPE validator issues using SYSTEM
solved it.  Checking Neerav's example, no, for "direct input"
that doesn't help.  I confused that with a case where I needed
to bypass the validator's knowledge of a public identifier.

(IIRC that was a case where the official W3C DTD was updated,
 and the validator still had the old DTD in its own SGML-lib.)

Because I had no clue what the problem in Neerav's example is,
I tried to add encoding="US-ASCII".  That results in an error:

| Character Encoding mismatch!

| The character encoding specified in the XML declaration

With his unmodified example I get no such error, and if I try
to add encoding="UTF-8" it's also okay.  The info "I will use
the value from the XML declaration (utf-8)" is erroneous, I had
added encoding="US-ASCII".

Okay, but in that case the validator was already confused about
SGML vs. XML, and said "Parsing will continue in SGML mode".
