title: chef - precedence of attributes set on node level
body: <p>Maybe I missed something in the doc's, but after reading the order that attributes are used when defined in multiple places I don't understand where attributes set at the <strong>node level</strong> come into the equation</p>
  
  <p>In the 1 to 15 levels of where attributes can be set and overridden, it mentions recipe, environment, role, attribute file but it never seems to mention what happens to attributes defined on a node, say by <code>knife node edit ...</code></p>
  
  <p>It looks like you can only define attributes of <em>normal</em> type on a node? Normal attributes are only mentioned for priority levels 7 and 8 in the list... attribute files and recipes respectively. </p>
  
  <p>So if I set an attribute on the node that was also defined on the environment and role levels who wins?</p>
