Sure, but my question was how far should we go? For example, this is  
a valid doctype declaration:

     <!DOCTYPE note [
       <!ELEMENT note (to,from,heading,body)>
       <!ELEMENT to      (#PCDATA)>
       <!ELEMENT from    (#PCDATA)>
       <!ELEMENT heading (#PCDATA)>
       <!ELEMENT body    (#PCDATA)>
     ]>

Should we support it? (Browsers support this correctly only for xml  
mime types.)

What about comments inside it (delimited by `--`)?

     <!DOCTYPE note [
       <!ELEMENT note (to,from,heading,body)>
       <!ELEMENT to      (#PCDATA)>
       <!ELEMENT from    (#PCDATA)>
       <!ELEMENT heading (#PCDATA)>
       <!ELEMENT body    (#PCDATA)>
       -- this is ]> a comment --
     ]>

And what about quoted text inside it?

So we have the choice of supporting this loosely like browsers do  
with a text/html mime type or we could support it fully according to  
the xml spec, which is not a trivial task. Or we could do something  
in the middle.

That was the essence of my question.

I think the answer (for `<!`) is obvious: there is not much value in  
supporting this currently. But it's still good to know that this  
limitation exists.

As for `<%` and `<@`, I've never used them so I don't even know what  
is the correct closing marker. Is it `<@  @>` or just `<@  >`? Is  
there any special consideration to take into account?
