<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>The sharing analysis of tree t is the annotation of all its subtrees t' with their number of occurences in t. </p>
<p>As this annotation of t' depends of a context (the tree t for which t' is a subtree) a specific property key unique to each sharing analysis must be generated. </p>
