What to use for an empty word?

I am writing code for a new tag, \li3, that is used to make generic 
lists with the style of \param, \retval, etc. It should take two words 
followed by a paragraph, however the first word should be optional. 
Therefore I want to be able to specify a null 'placeholder'. I am 
thinking about using '-' but thought I would see if there are any 
suggestions. (If there is already something that can be used as an empty 
placeholder, I have not found it.)

Example (different implementation of \param):
\par Parameters:
\li3 <tt>in</tt> foo A silly argument

The above is equivalent to:
\param[in] foo A silly argument
