fn:snapshot
Makes a deep copy of a sequence, such that any node in the sequence is copied together with a shallow copy of its ancestors and their attributes. (This will typically be a streamed node, to allow navigation within the subtree rooted at the node.) The zero-argument form applies the function to the context item.
