And the reason why Item was chosen to mean this is some "thing" that 
should be treated  as its own object...

Its a bit vague it basically means  haudio has a way of calling the same 
class names in different contexts and not get the two confused..

<div class="haudio">
    <span class="htitle">Great Playlist</span>
    <span class="item">
          <span class="htitle">Great track</span>

Dont get me wrong I am not saying lets use "item" or "mfo" or any such 
word, what I am saying is items parsing rule *can* be applied to all 
root class microformats,  hcard already has a similar rule ...

For what it's worth I feel a little like a dog chasing my own tail , 
because I am not sure this is an authoring issue just a parser issue.
