I would try to avoid heredoc delimiters of a single character, just in case ;)
What I tend to do is to use <<<EOC where the last letter changes depending on
what content I'm outputting. It makes no difference, but reading back later
it helos me understand what I was doing. So I'd use EOX for XML, EOF for
forms, OEC for general content, etc.
I only do it this way because I remember reading somewhere (If forget exactly
where now) that it is better to use 3 or more characters in uppercase so they
stand out well from the rest of the code.
