* <xsd:complexType name="GetFeatureType">
* <xsd:annotation>
* <xsd:documentation>
* A GetFeature element contains one or more Query elements
* that describe a query operation on one feature type. In
* response to a GetFeature request, a Web Feature Service
* must be able to generate a GML3 response that validates
* using a schema generated by the DescribeFeatureType request.
* A Web Feature Service may support other possibly non-XML
* (and even binary) output formats as long as those formats
* are advertised in the capabilities document.
* </xsd:documentation>
* </xsd:annotation>
* <xsd:complexContent>
* <xsd:extension base="wfs:BaseRequestType">
* <xsd:sequence>
* <xsd:element maxOccurs="unbounded" ref="wfs:Query"/>
* </xsd:sequence>
* <xsd:attribute default="results" name="resultType"
* type="wfs:ResultTypeType" use="optional">
* <xsd:annotation>
* <xsd:documentation>
* The resultType attribute is used to indicate
* what response a WFS should return to user once
* a GetFeature request is processed.
* Possible values are:
* results - meaning that the full response set
* (i.e. all the feature instances)
* should be returned.
* hits - meaning that an empty response set
* should be returned (i.e. no feature
* instances should be returned) but
* the "numberOfFeatures" attribute
* should be set to the number of feature
* instances that would be returned.
* </xsd:documentation>
* </xsd:annotation>
* </xsd:attribute>
* <xsd:attribute default="text/xml; subtype=gml/3.1.1"
* name="outputFormat" type="xsd:string" use="optional">
* <xsd:annotation>
* <xsd:documentation>
* The outputFormat attribute is used to specify the output
* format that the Web Feature Service should generate in
* response to a GetFeature or GetFeatureWithLock element.
* The default value of 'text/xml; subtype=gml/3.1.1'
* indicates that the output is an XML document that
* conforms to the Geography Markup Language (GML)
* Implementation Specification V3.1.1.
* For the purposes of experimentation, vendor extension,
* or even extensions that serve a specific community of
* interest, other acceptable output format values may be
* used to specify other formats as long as those values
* are advertised in the capabilities document.
* For example, the value WKB may be used to indicate that a
* Well Known Binary format be used to encode the output.
* </xsd:documentation>
* </xsd:annotation>
* </xsd:attribute>
* <xsd:attribute name="maxFeatures" type="xsd:positiveInteger" use="optional">
* <xsd:annotation>
* <xsd:documentation>
* The maxFeatures attribute is used to specify the maximum
* number of features that a GetFeature operation should
* generate (regardless of the actual number of query hits).
* </xsd:documentation>
* </xsd:annotation>
* </xsd:attribute>
* <xsd:attribute name="traverseXlinkDepth" type="xsd:string" use="optional">
* <xsd:annotation>
* <xsd:documentation>
* This attribute indicates the depth to which nested property
* XLink linking element locator attribute (href) XLinks are
* traversed and resolved if possible. A value of "1"
* indicates that one linking element locator attribute
* (href) Xlink will be traversed and the referenced element
* returned if possible, but nested property XLink linking
* element locator attribute (href) XLinks in the returned
* element are not traversed. A value of "*" indicates that
* all nested property XLink linking element locator attribute
* (href) XLinks will be traversed and the referenced elements
* returned if possible. The range of valid values for this
* attribute consists of positive integers plus "*".
* If this attribute is not specified then no xlinks shall be
* resolved and the value of traverseXlinkExpiry attribute (if
* it specified) may be ignored.
* </xsd:documentation>
* </xsd:annotation>
* </xsd:attribute>
* <xsd:attribute name="traverseXlinkExpiry"
* type="xsd:positiveInteger" use="optional">
* <xsd:annotation>
* <xsd:documentation>
* The traverseXlinkExpiry attribute value is specified in
* minutes. It indicates how long a Web Feature Service
* should wait to receive a response to a nested GetGmlObject
* request.
* This attribute is only relevant if a value is specified
* for the traverseXlinkDepth attribute.
