- View and attribute lookup order was changed to the following:
    1. Unacquired attributes
    2. Views
    3. Acquired attributes
  According to consensus in z3-five mailing list:
  http://codespeak.net/pipermail/z3-five/2006q2/001474.html

- The defaultView directive now only looks up views, not 
  attributes.

Fixed edge case of attribute name ''.
