Right. I think the xltxtra package even provides a \namedglyph macro  
or something like that to encapsulate this.

It should work to say something like (in plain XeTeX):

   \font\ornament="Minion Pro:+ornm=21"  {\ornament •}

or in xelatex, if you've already selected the font:

   {\addfontfeature{RawFeature={+ornm=21}}•}
