A couple of quick remarks on the example

Fabio et al:
a) I want to take a little more time to look at the system of URIs for
crossreferences.  I can't really tell what assumptions it embeds about
either the contents of the strings or the method of dereferencing them,
but that's mostly a product of my own ignorance, I imagine.
b)  Can this schema accomodate the following example gracefully?  "It shall be illegal to  + dance around the room + sing silly songs + remove certain articles of your clothing + discuss the baseball case at legal AI conferences  except on Tuesday"  t.  -- +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ Thomas R.
