I'm trying to REST POST a sequence of commands in accordance with

http://docs.basex.org/wiki/Commands#XML_Syntax

I get the error response:

cvc-elt.1: Cannot find the declaration of element 'commands'.

Is there a namespace for <commands> wrapper element? I'd expect it to be  

http://basex.org/rest

but the same message is returned on the qualified name:

cvc-elt.1: Cannot find the declaration of element 'basex:commands'.

Using Basex 8.5.3

Thanks in advance,
