40 9.4 Exceptions
In the event that a web feature service encounters an error servicing a GetFeature request, it shall raise an exception as described in subclause 7.7.
9.5 Examples
This section contains numerous examples of the GetFeature request. Some examples include sample output.
Example 1
This example fetches a specific instance of the feature type InWaterA_1M identified by the feature identifier InWaterA_1M.1234.

Example 2
This example fetches a subset of properties of the feature type InWaterA_1M. The specific instance that is retrieved by the request is identified by the feature identifier
InWaterA_1M.1013.

41
In this example, all the properties of feature type InWaterA_1M are fetched for an enumerated list of feature instances. The GmlObjectId element is used to identify
each feature to be fetched.
?xml version=1.0 ? GetFeature

GetFeature
Example 4
This example is similar to the previous example except in this case only some of the properties of an enumerated set of features are fetched. The PropertyName element
is used to list the properties to be retrieved.
?xml version=1.0 ? GetFeature
version=1.1.0 service=WFS

GetFeature
Example 5
Select all instances of the feature type InWaterA_1M to a maximum of 10000 features.
?xml version=1.0 ? GetFeature
version=1.1.0 service=WFS
