Good idea.

If this the purpose, it might be better to call it something different, 
like  <sampleValue>.  "Default" usually refers to a value that is assumed 
when none is provided.  For some parameters, assuming a default is not 
appropriate.  

(Mental sticky: we also need a way to indicated required parameters.)
