  <xsd:complexType name="QueryType">
      <xsd:annotation>
          <xsd:documentation>
              The Query element is of type QueryType.

                      <xsd:documentation>
                     The Property element is used to specify one or more
                     properties of a feature whose values are to be retrieved
                     by a Web Feature Service.
                     While a Web Feature Service should endeavour to satisfy
                     the exact request specified, in some instance this may
                     not be possible.  Specifically, a Web Feature Service
                     must generate a valid GML3 response to a Query operation.
                     The schema used to generate the output may include
                     properties that are mandatory.  In order that the output
                     validates, these mandatory properties must be specified
                     in the request.  If they are not, a Web Feature Service
                     may add them automatically to the Query before processing
                     it.  Thus a client application should, in general, be
                     prepared to receive more properties than it requested.
                     Of course, using the DescribeFeatureType request, a client
                     application can determine which properties are mandatory
                     and request them in the first place.

                     A function may be used as a select item in a query.
                     However, if a function is used, care must be taken
                     to ensure that the result type matches the type in the

                  The Filter element is used to define spatial and/or non-spatial
                  constraints on query.  Spatial constrains use GML3 to specify
                  the constraining geometry.  A full description of the Filter
                  element can be found in the Filter Encoding Implementation
                  Specification.

              <xsd:annotation>
                  <xsd:documentation>
                  The SortBy element is used specify property names whose
                  values should be used to order (upon presentation) the
                  set of feature instances that satisfy the query.

              <xsd:documentation>
                 The handle attribute allows a client application
                 to assign a client-generated identifier for the
                 Query.  The handle is included to facilitate error
                 reporting.  If one Query in a GetFeature request
                 causes an exception, a WFS may report the handle
                 to indicate which query element failed.  If the a
                 handle is not present, the WFS may use other means
                 to localize the error (e.g. line numbers).

      <xsd:attribute name="typeName" type="wfs:TypeNameListType" use="required">
          <xsd:annotation>
              <xsd:documentation>
                The typeName attribute is a list of one or more
                feature type names that indicate which types
                of feature instances should be included in the
                reponse set.  Specifying more than one typename
                indicates that a join operation is being performed.
                All the names in the typeName list must be valid
                types that belong to this query's feature content
                as defined by the GML Application Schema.

      <xsd:attribute name="featureVersion" type="xsd:string" use="optional">
          <xsd:annotation>
              <xsd:documentation>
                For systems that implement versioning, the featureVersion
                attribute is used to specify which version of a particular
                feature instance is to be retrieved.  A value of ALL means
                that all versions should be retrieved.  An integer value
                'i', means that the ith version should be retrieve if it
                exists or the most recent version otherwise.
             </xsd:documentation>

      <xsd:attribute name="srsName" type="xsd:anyURI" use="optional">
          <xsd:annotation>
              <xsd:documentation>
                This attribute is used to specify a specific WFS-supported SRS
                that should be used for returned feature geometries.  The value
                may be the WFS StorageSRS value, DefaultRetrievalSRS value, or
                one of AdditionalSRS values.  If no srsName value is supplied,
                then the features will be returned using either the
                DefaultRetrievalSRS, if specified, and StorageSRS otherwise.
                For feature types with no spatial properties, this attribute
                must not be specified or ignored if it is specified.

    Overrides to return the value of the "typeName" attribute as a single String instead of a List. Otherwise typeName gets encoded as the QueryType.getTypeName() toString's value which depends on the toString implementation of the internal java.util.List.
    Also, if the requested property is "SortBy" and the QueryType has an empty sortby list, returns null to avoid encoding an empty sortBy list
    
    Specified by:
    
    getProperty in interface ComplexBinding
    
    Overrides:
    
    getProperty in class AbstractComplexEMFBinding
    
    Parameters:
    
    object - The object being encoded.
    
    name - The name of the property to obtain.
    
    Returns:
    
    The value of the property, or null.
    
    Throws:
    
    Exception
