namespaces [--registered|:r] [expression]

For each node in a given node-list lists all namespaces that are valid the scope of the node. Namespaces are listed in the form of xmlns:prefix="uri" declarations, preceded by a canonical xpath of the corresponding node on a separate line.

If --registered or :r flag is used, list also namespaces registered with the register-namespace command in XSH syntax.

If called without the --registered flag and no xpath is given, lists namespaces in the scope of the current node.
