I haven't debugged that, but looks like it's one of them. However, I 
wouldn't call that a bug. In the world of XSLT transformers usually 
strip comments (allthough you can match it with comment() and copy it 
again).
But in this specific case it is really a problem, and since the two 
transformers are kind of "hidden" they should really do full copy of 
every node.

In some places I need to generate it dynamically. And I don't want to 
create *.js files for such small script snippets.
