*Removing* things is nevertheless destructive - it seems like a bad 
decision to make it do that without *always* warning first.

What I meant was that Amaya doesn't restore the doctype despite that 
the doctype is unknown to it. By contrast, for the XHTML mode, then 
Amaya will - when you leave the source editor, restore the DOCTYPE if 
it feels for it.

PS: Do you know if the group that looks at making Amaya 
HTML5-compatible is going to implement both a text/html mode and a 
xhtml mode? Or if they perhaps are aiming for a polyglot mode? 

PPS: Currently, the <?xml version="1.0" encoding="UTF-8"?> declaration 
is used as an XHTML mode trigger, it seems. This is bad, as it prevents 
us from making polyglot HTML (as the XML declaration is invalid in 
text/html). Plus that there is no need to declare the encoding for XML 
as long as one uses UTF-8.

If the team decides to implement HTML5 as a polyglot mode, then 
something that separates HTML and XHTML mode isn't really needed. But 
if it *does* need a trigger at the beginning of the document for this, 
then I suggest that they utilize the HTML5 doctype, like so:

a) <!doctype html> is only text/html compatible and could thus
   trigger that mode. (It causes fatal XML error.)
b) <!DOCTYPE html> is both text/html and XHTML-compatible, and
   could thus trigger XHTML mode.
