XQL and proximal nodes

We consider the recently proposed XQL language, which is designed to query XML documents by content and structure. We show that an already existing model, namely \Proximal Nodes", is the only one that addresses all the complex querying operations de ned by XQL and that suggests an e cient implementation for them.
