This is a marker interface used to identify nodes that contain a namepool fingerprint. Although all nodes
are capable of returning a fingerprint, some (notably DOM, XOM, and JDOM nodes) need to calculate it on demand.
A node that implements this interface indicates that obtaining the fingerprint for use in name comparisons
is more efficient than using the URI and local name.
