Telling Zope/Chameleon to not parse a section?

I have a Pyramid app that uses Chameleon. I need to declare some attributes in my DOCTYPE, like so:

<!DOCTYPE public 开发者_运维知识库html .........
[
    <!ATTLIST tag attributes CDATA #IMPLIED>
]>

When I add this to my template, id doesn't get rendered properly and my browser draws "]>".

When I remove the ATTLIST and only do <!DOCTYPE public html .........>, everything works.

How can I tell Chameleon to not parse the ATTLIST section and copy it as is?

That has absolutely nothing to do with Chameleon. If I paste that code into a file and open it in my browser, I see ]> as well.

Edit: I figured it out. Rename the file to .xhtml and it will work (at least for me).

If you're receiving it over the network, having the content-type set to application/xhtml+xml would work the same way.
