Trouble: 'Error tag name "xxf:submission" is not allowed'

> All,
>
> having some problem after upgrading to version 3.5M1. I have attached
> the stack trace and the offending code:
>
>  > org.orbeon.oxf.common.ValidationException: null, line 0, column 0:
> Error tag name "xxf:submission" is not allowed. Possible tag names are:
> <divs>(schema:
>  > oxf:/ops/xforms/xforms-server-response.rng)
>  > null, line 0, column 0: Error tag name "xxf:submission" is not
> allowed. Possible tag names are: <divs>(schema:
> oxf:/ops/xforms/xforms-server-response.rng )
>
> Steps to reproduce:
> 1. Load attached all.knowledgebases.test.xml
> 2. Click on link named 'edit knowledgebase'
> 3. Note the XForms error in the tomcat log
>
> Not sure if I am doing something wrong, or if this is a bug. Any help or
> tips would be appreciated :-)
>
> Thanks!
