RE: [xsl] HOWTO: Internet Explorer conditional comments in XSLT 1.0

I'm not sure you emphasize strongly enough the key limitation in this
approach: in the data model, comments cannot contains elements, they can
only contain strings; so you need to construct your content as a string in
which the markup is hand-generated. If the stuff between IE's conditional
comments gets complicated then this is going to become a pain, especially if
you have to produce it by modifying existing stylesheets that were designed
to produce the content as real element trees.

The stuff on result-tree-fragments is a bit tangential. The content could
just as well be a string. There's no special RTF "magic" here. All that's
happening is that when a string contains the "<" character, and the string
is used to form the body of a comment, the "<" is left as a "<" and isn't
escaped to "&lt;".

Incidentally, you also have to worry about the fact that the comment can't
contain "--" (and therefore, can't contain nested comments).
