Does it mean the WFS server must not mix features of type A and B in the response? What if it is able to do some optimization like select both feature types by one query to db?

Is it possible to define one sort over more queries in one GetFeature request? Let's have this request: 

<GetFeature>
   <Query typeName="River"/>
   <Query typeName="Creek"/>
</GetFeature>

and I want to sort both rivers and creeks together by their common propety e.g. "Name".

Thanks Ctibor
