 * The properties in the "/__symbols__" node are "symbols".

 *

 * The value of properties in the "/__symbols__" node is the path of a

 * node in the subtree of a fragment node's "__overlay__" node, for

 * example "/fragment@0/__overlay__/symbol_path_tail".  Symbol_path_tail

 * can be a single node or it may be a multi-node path.

 *

 * The duplicated property value will be modified by replacing the

 * "/fragment_name/__overlay/" portion of the value  with the target

 * path from the fragment node.
