Interchange provided facilities to pass arguments in the URL without 
disrupting normal behavior. For a simple argument:

         <a href="[area href=foo arg=bar]">foobar</a>

For multiple arguments:

         <a href="[area
                         href=foo
                         form="
                         var1=value1
                         var2=value2
                         var3=value3
         "]">fooform</a>
