    owsDomainType.xsd
    This XML Schema Document encodes the allowed values (or
    domain) of a quantity, often for an input or output parameter to an OWS.
    Such a parameter is sometimes called a variable, quantity, literal, or
    typed literal. Such a parameter can use one of many data types, including
    double, integer, boolean, string, or URI. The allowed values can also be
    encoded for a quantity that is not explicit or not transferred, but is
    constrained by a server implementation.
    
    OWS is an OGC Standard.

      Valid domain (or allowed set of values) of one quantity,
      with its name or identifier.
    
    
      
        
          
            Name or identifier of this
            quantity.
          
        
      
    
  
  
  
    
      Valid domain (or allowed set of values) of one quantity,
      with needed metadata but without a quantity name or
      identifier.
    
    
      
      
        
          Optional default value for this quantity, which
          should be included when this quantity has a default
          value.
        
      
      
        
          Meaning metadata should be referenced or included for
          each quantity.
        
      
      
        
          This data type metadata should be referenced or
          included for each quantity.
        
      
      
        
          Unit of measure, which should be included when this
          set of PossibleValues has units or a more complete reference
          system.
        
      
      
        
          Optional unordered list of other metadata about this
          quantity. A list of required and optional other metadata elements
          for this quantity should be specified in the Implementation
          Specification for this service.
        
      
    
  
  
  
    
      Specifies the possible values of this
      quantity.
    
    
      
      
      
      
    
  
  
  
    
      Specifies that any value is allowed for this
      parameter.
    
    
  
  
  
    
      Specifies that no values are allowed for this parameter
      or quantity.
    
    
  
  
  
    
      Reference to externally specified list of all the valid
      values and/or ranges of values for this quantity. (Informative: This
      element was simplified from the metaDataProperty element in GML
      3.0.)
    
    
      
        
          
            Human-readable name of the list of values provided
            by the referenced document. Can be empty string when this list has
            no name.
          
          
        
      
    
  
  
  
    
      Indicates that this quantity has units or a reference
      system, and identifies the unit or reference system used by the
      AllowedValues or ValuesReference.
    
    
      
        
          Identifier of unit of measure of this set of values.
          Should be included then this set of values has units (and not a more
          complete reference system).
        
      
      
        
          Identifier of reference system used by this set of
          values. Should be included then this set of values has a reference
          system (not just units).
        
      
    
  
  
  
  
    
      List of all the valid values and/or ranges of values for
      this quantity. For numeric quantities, signed values should be ordered
      from negative infinity to positive infinity.
    
    
      
        
        
      
    
  
  
  
  
  
    
      A single value, encoded as a string. This type can be
      used for one value, for a spacing between allowed values, or for the
      default value of a parameter.
    
    
      
    
  
  
  
    
      The default value for a quantity for which multiple
      values are allowed.
    
  
  
  
  
  
    
      A range of values of a numeric parameter. This range can
      be continuous or discrete, defined by a fixed spacing between adjacent
      valid values. If the MinimumValue or MaximumValue is not included, there
      is no value limit in that direction. Inclusion of the specified minimum
      and maximum values in the range shall be defined by the
      rangeClosure.
    
    
      
      
      
        
          Shall be included when the allowed values are NOT
          continuous in this range. Shall not be included when the allowed
          values are continuous in this range.
        
      
    
    
      
        Shall be included unless the default value
        applies.
      
    
  
  
  
    
      Minimum value of this numeric parameter.
    
  
  
  
    
      Maximum value of this numeric parameter.
    
  
  
  
    
      The regular distance or spacing between the allowed
      values in a range.
    
  
  
  
    
      Specifies which of the minimum and maximum values are
      included in the range. Note that plus and minus infinity are considered
      closed bounds.
    
    
      
        
          
            The specified minimum and maximum values are
            included in this range.
          
        
        
          
            The specified minimum and maximum values are NOT
            included in this range.
          
        
        
          
            The specified minimum value is NOT included in this
            range, and the specified maximum value IS included in this
            range.
          
        
        
          
            The specified minimum value IS included in this
            range, and the specified maximum value is NOT included in this
            range.
          
        
      
    
  
  
  
  
    
      References metadata about a quantity, and provides a name
      for this metadata. (Informative: This element was simplified from the
      metaDataProperty element in GML 3.0.)
    
    
      
        
          Human-readable name of the metadata described by
          associated referenced document.
        
        
      
    
  
  
  
    
      Reference to data or metadata recorded elsewhere, either
      external to this XML document or within it. Whenever practical, this
      attribute should be a URL from which this metadata can be electronically
      retrieved. Alternately, this attribute can reference a URN for
      well-known metadata. For example, such a URN could be a URN defined in
      the "ogc" URN namespace.
    
  
  
  
    
      Definition of the meaning or semantics of this set of
      values. This Meaning can provide more specific, complete, precise,
      machine accessible, and machine understandable semantics about this
      quantity, relative to other available semantic information. For example,
      other semantic information is often provided in "documentation" elements
      in XML Schemas or "description" elements in GML objects.
    
  
  
  
    
      Definition of the data type of this set of values. In
      this case, the xlink:href attribute can reference a URN for a well-known
      data type. For example, such a URN could be a data type identification
      URN defined in the "ogc" URN namespace.
    
  
  
  
    
      Definition of the reference system used by this set of
      values, including the unit of measure whenever applicable (as is
      normal). In this case, the xlink:href attribute can reference a URN for
      a well-known reference system, such as for a coordinate reference system
      (CRS). For example, such a URN could be a CRS identification URN defined
      in the "ogc" URN namespace.
    
  
  
  
    
      Definition of the unit of measure of this set of values.
      In this case, the xlink:href attribute can reference a URN for a
      well-known unit of measure (uom). For example, such a URN could be a UOM
      identification URN defined in the "ogc" URN namespace.
