+pubsub/node/schema: nodes schema handling
+=========================================
+
+``node schema`` is an experimental feature to associate a data form with a PubSub node, and
+reject items not following this form. This feature is currently only available with SàT
+PubSub.
+
+Those commands can only be used by an owner of the node.
+
+set
+===
+
+Set the schema of a node. The raw schema is written directly as positional argument.
+
+example
+-------
+
+Set the schema for tickets node using the file ``tickets_schema.xml`` from ``$HOME``
+directory. Shell substition is used here to put the content of the file in the positional
+argument::
+
+  $ li pubsub node schema set -n org.salut-a-toi.tickets:0 -s pubsub.example.org "$(<~/test_schema.xml)"
+
+
+edit
+====
+
+Edit the schema of a node using your local editor (the one set in ``$EDITOR``).
+
+If you don't change anything or publish an empty schema, the edition will be cancelled.
+
+:ref:`draft_common` commands can be used.
+
+example
+-------
+
+Edit the tickets node schema::
+
+  $ li pubsub node schema edit -n org.salut-a-toi.tickets:0 -s pubsub.example.org
+
+
+example
+-------
+
+get
+===
+
+Retrieve schema of a node.
+
+example
+-------
+
+Get schema of tickets and save it to a file named ``tickets_schema.xml`` in ``$HOME``
+directory::
+
+  $ li pubsub node schema get -n org.salut-a-toi.tickets:0 -s pubsub.example.org > ~/tickets_schema.xml
