| I'm not sure if this is a good idea. Because once Zope3's macros are XML
| mode, all other templates using those macros need to be XML mode. That,
| in turn, means that all templates need to carry the <?xml ...?>
| processing instruction because that's the only way XML mode is currently

| namespace declarations which are mandatory), I wouldn't want to force it

Don't forget that IE will then have an insane tendency to render the
pages wrong.  I don't recall all of the details, but it was something
like if the document began with <?xml ?> IE would switch to "quirks
mode" and do funny things with boxes, margins, and the overall layout.
The details are in this list's archives (if they aren't it's in the
zope at zope.org list archives).

(not that I'm a fan of IE, but I do recall that being a problem for
some people)
