EXAMPLE 2 The following fragment illustrates a response to GetFeature operations that contains multiple query

wfs:FeatureCollection
Feature members that satisfy more than one query expression in a GetFeature operation shall appear in one collection and be referenced by all others.
The order of the collections in the response document shall be the same as the order of the query expressions in the GetFeature request; although the queries may be processed in any order the server desires.
11.3.3.6 Join query response
If a GetFeature operations contain a query expression that is performing a join, a server shall use the wfs:Tuple element see 10.3.2 to report all tuples of features that satisfy the join predicate.
EXAMPLE 1 The following XML fragment shows the response generated by a query expression joining three feature
types ns1:FeatureTypeOne, ns1:FeatureTypeTwo and ns2:FeatureTypeThree:

GetFeature operations that contain a mix of join and non-join query expressions can contain component feature collections containing a mixture of wfs:member and wfs:Tuple elements.

join and non-join query expressions.
