namespaces in the content of the direct element constructors

Hello,

Please, could you answer the following question:
In the "3.7.1.3 Content" section of the XQuery 1.0 there is the discription
of
the content of the direct element constructor.
Unlike from the same description of the content of the computed element
constructor there is nothing said about namespace nodes.

Is this implies, that there shouldn't be any namespace nodes in "content
sequence"?

For instance, consider the following expression
<a:b>{namespace a {"http://example.org/v1"} </a:b>

Is it correct?

Regards,
Leonid Novak.
