Arguments

   <xMinAttr>

      The name of the attribute assigned the minimum value of the feature along 
      the X axis.

      Range: String

   <xMaxAttr>

      The name of the attribute assigned the maximum value of the feature along 
      the X axis.

      Range: String

   <yMinAttr>

      The name of the attribute assigned the minimum value of the feature along 
      the Y axis.

      Range: String

   <yMaxAttr>

      The name of the attribute assigned the maximum value of the feature along 
      the Y axis.

      Range: String

   <zMinAttr>

      The name of the attribute assigned the minimum value of the feature along 
      the Z axis.

      Range: String

   <zMaxAttr>

      The name of the attribute assigned the maximum value of the feature along 
      the Z axis.

      Range: String

   GEOMETRIC

      If specified, the geometric bounding box will be returned.

      Range: N/A
      
   <widthAttr>

      The name of the attribute assigned the width of the minimum oriented 
      bounding box. Its value will always be less than or equal to that of 
      <lengthAttr>.

      Range: String

   <lengthAttr>

      The name of the attribute assigned the length of the minimum oriented 
      bounding box. Its value will always be greater than or equal to that of 
      <widthAttr>.
      
      Range: String

Description

   This function extracts the bounds of a feature. It determines the extreme 
   values of the feature in each of the x and y (and optionally z) axes, and 
   assigns these values to the attribute names passed in as arguments.
   
   The zMinAttr and zMaxAttr are optional, and are set to the minimum values on 
   the Z axis of the feature. If the feature has only two dimensions, both 
   zMinAttr and zMaxAttr will be set to 0.
   
   Normally the @Bounds function considers the bounding box of the feature to be 
   the bounding box of all the coordinates in the feature. If the last argument 
   to the function is the string GEOMETRIC, the function will return the 
   geometric bounding box of the feature, which in the case of some point 
   features may be different. For example, text features only have a single 
   coordinate (to specify their location), so normally their bounding box only 
   contains that single point. However, if the GEOMETRIC flag is specified, the 
   returned bounding box will contain the entire feature, as if it were rendered 
   with a fixed-width font at its given height. Arcs and ellipses are treated 
   similarly.
  
   When using the GEOMETRIC flag, please note that the generic form of any 
   geometry attributes are required to exist on the feature in order to properly 
   determine the bounds. For example, a text feature should have an fme_type 
   attribute with a value of fme_text, and other geometry attributes that 
   describe a text geometry such as fme_text_string, should also be present.
  
   If MIN_BOUNDING is specified as the first parameter, the function will 
   compute the minimum oriented bounding box instead of the axis-aligned or 
   rectilinear bounding box. The widthAttr and lengthAttr are optional, and are 
   set to the width and length of the minimum oriented bounding box, 
   respectively. 
  
      Note: The value of widthAttr will always be less than or equal to 
      lengthAttr.

TO BE RESOLVED

   MIN_BOUNDING is not documented in the Arguments section.
