Look at the error message. See how "show-adv-attributes?fact" is
smooshed together? In assembling your String, you've neglected to put
a space or newline in between the name of the rule and the variable
that first pattern is bound to. '?' is a legal character in names
(for better or for worse.) So anyway, that's why there's an error on
this rule.
There no difference at all between the syntax accepted by
"executeCommand()" and the syntax you use in a .clp file -- the same
parser reads them both.
