 However, LD Patch provides mechanisms to address those pre-existing blank nodes: <a>bind</a>ing a variable to a blank node reachable through a <a>path expression</a>, <a>cut</a>ting a whole tree made of blank nodes, or using <a>UpdateList</a> to deal with those blank nodes that constitute RDF collections. There are cases where those mechanisms will not be able to unambiguously address a given blank node, but those cases are deemed <a href="#pathological-graph">pathological</a>, and are out of the scope of this specification.
