The DTD for struts 1.0 and 1.1 has the form bean as an attribute, of
which there can only be one. Therefore, your individual _action_ can
only have one form; however, if is possible that a single display page
could be used as the output of more than one action, with the potential
for different forms. This would really be ugly, in that you would need
to code the page itself to detect which form it was working
on...clearly not a good practice. Either way, it would not screw up the
default alias trick.
