Probleem met query's op SQL Server XML-naamruimte

Begrepen... natuurlijk, direct na het vragen

    ;WITH XMLNAMESPACES (N'http://schemas.microsoft.com/dynamics/2006/02/documents/EntityKey' as DYN)
    SELECT  IDENTITY(int,1,1)   
                as 'ID',
            c.value('(DYN:KeyData/DYN:KeyField/DYN:Value)[1]', 'VARCHAR(40)')
                as 'JournalNum'
    INTO    #tmpBatches
    FROM    @ResultData.nodes('//EntityKey') t(c)
