$( doesn't work, and ${ does. :-)
(Incidentally, the "${" looks like a ":-)" type figure for a man who's
blinded by money.)
Note that nothing prohibits you from having an attribute value that
looks like
"$(2 + 2)"
This, however, simply evaluates to the literal string "$(2 + 2)" and is
not interpreted as an expression. "${2 + 2}" evaluates to 4.
