+-   The ``xmlattr`` filter does not allow keys with ``/`` solidus, ``>``
+    greater-than sign, or ``=`` equals sign, in addition to disallowing spaces.
+    Regardless of any validation done by Jinja, user input should never be used
+    as keys to this filter, or must be separately validated first.
