Sounds good.

You are proposing this:
   Master
   ↳ Object
      ↳ List
with the rationale: 'list is an object with an items attribute added'  
Right?
(hope the arrows come thru allright)


Two alternatives perhaps worth considering:

1. Reverse the inheritance, so:
   Master
   ↳ List
      ↳ Object
with the rationale: 'object is a list where the items attribute is  
limited to 1 'thing''

2. Refactor into Items object and Decorate when needed
   Master
   ↳ Object

   ItemList

with the rationale: 'when we need a list, we decorate Object with an  
instance of Values and work from there. The latter is actually the  
same as 1 (because the items attribute would still be needed), but  
refactored one step further.

I'm just giving them for inspiration, I have no clear preference,  
still being out of sync with what the current code is.

PS
Did I see it right that the branch I pushed without <xar:mlstring/>  
tags was merged in? (i.e the merge + the many debris revisions?)
