I don't think the above works, really.  I would expect it to be written:

<dtml-var "_[style_sheet]">, but this will render the stylesheet, not
it's url, and (surprisingly) <dtml-var "_[style_sheet].absolute_url()">
will *not* work.

The most consistent way to dereference a string is:

<dtml-var "_.getitem(style_sheet).absolute_url()">
