First, yes you are right, attributes are set at parse time right now.

If you want to throw a BuildException on malformed attributes execute
is your only clean choice - as the setters shouldn't throw any
Exceptions at all. If you just want to print a warning you can do it
in the setter method.

In some cases execute is your only choice anyway - when two attributes
depend on each other for example.
