title: Use of MixinTypes in JCR
body: <p>I was trying to understand the concept of MixinTypes in JCR, What i red "Mixin node types usually specify additional properties or child nodes related to a capability being added to the node" but it seems some unclear, I am looking for simple defination through which i can understand. Like we have node type <code>cq:page</code> and it has supertype <code>mix:created</code> which is of mixin type. What if the case i remove mixin type property from <code>mix:created</code>.</p>
  
  <p>Or any other example.
  Thanks </p>
