Nope ... it is entirely necessary ... the quoted format '() essentially
tells the DSSSL engine that "whatever I'm writing in these parentheses,
take the values as given, not as evaluated", so all ancestral list
operators on the return value of a called procedure must be the list
function and not the quoted form.

Thus, when doing many attributes, you can only quote those which are known
at compile time, as in the following example:

    attributes: (list '("BORDER" "0")
                      (list ("SRC" (attribute-string "filename"))))

I hope this helps.
