The user can presumably turn off the warning flag. Or a tool can recognize
(and ignore) attributes from outside its domain. The alternative is for the
designer to type an extra "synthesis, " with every attribute.
Cliff, you probably have a good sense of how many pragmas appear in a
typical design, excluding "translate on/off", which is more like #ifdef than
an attribute. If all the pragmas are translated into attributes, and if, in
the worst case, all the attributes are misspelled, how many warnings would
occur in a typical design?
