I don't think we should need any special cludges just to support this
usecase. 8-)

Give two a completely bogus, impossible to be used in any real world
usage value and check for that.  Should be easier than comparing it to
a literal ${one} or @one or whathever.

<macrodef name="macro">
    <attribute name="one"/>
    <attribute name="two" 
      default="nobody-with-a-sane-mind-would-ever-want-to-use-this-value"/>
</macrodef>
