functx:is-node-among-descendants-deep-equal
=========================================== 

Description
~~~~~~~~~~~
The functx:is-node-among-descendants-deep-equal function returns a boolean value 
indicating whether or not a node has the same contents as a node in a sequence, 
or one of the descendants of a node in the sequence. It determines whether the 
nodes have the same content using the built-in fn:deep-equal function. If $node 
or $seq is the empty sequence, it returns false.

For a similar function based on the identity of a node rather than its contents, 
see functx:is-node-among-descendants.
