   @Transform(<sourceFormat>,<destinationFormat>[,<linkAttributes>])
   
Arguments

   <sourceFormat>    
   
      The name of the format from which the feature was read.
      
      Range: any metafile in the metafiles directory OR FME_GENERIC
   
   <destinationFormat>     
   
      The name of the format that is the destination of the feature.
   
      Range: any metafile in the metafiles directory OR FME_GENERIC
      
   <linkAttributes>  
   
      Specifies whether the format-specific attributes should be linked to the 
      generic attributes. See below. Default is GEOMETRY.

      Range: (GEOMETRY|NAMES|TYPES|DEF_LINES|OVERWRITE_DEST_FORMAT_ATTRS|
              ALIAS_GEOMETRY|PRESERVE_GEOMETRY|SCHEMA)  
   
Description

   This function transforms a feature by adding the geometry attributes used by 
   the destination format to based on those supplied to the feature by the 
   source format. 

   For example, the MIF reader uses the special attribute mif_type to hold the 
   kind of entity that was read. The ACAD uses autocad_entity for this purpose. 
   When @Transform(MIF,ACAD) is invoked, an autocad_entity attribute will be 
   added to the feature with the appropriate value corresponding to the value of 
   mif_type. If the mif_type was mif_polyline, then the value for autocad_entity 
   will be autocad_line. Any additional attributes required by the 
   autocad_entity will also be created and given the correct values. If the 
   mif_type was mif_arc, then the value for mif_primary_axis would be added as 
   the value for autocad_primary_axis.

   A pseudo-format name called FME_GENERIC is available to convert from the 
   generic fme_type to and from specific format representations. The allowed 
   values for fme_type, together with any special attributes used, are described 
   in the FME Universal Translator on-line help files, in the section FME 
   Architecture. By default, all FME features have the FME_GENERIC attributes 
   when the mapping file. However, it is possible for operations in the mapping 
   file to lose these attributes.

   The <linkAttributes> parameter specifies whether the created format-specific 
   attributes will be "linked" to the generic FME attributes they came from. If 
   this parameter is set to ALIAS_GEOMETRY, then the attributes will be linked. 
   In this case, if either the format-specific or generic attribute is changed, 
   the other will be changed with it. In addition, if the fme_type attribute of 
   the feature is changed, the format-specific type attribute (for example, 
   igds_type) will be removed. If the <linkAttributes> parameter is set to 
   PRESERVE_GEOMETRY, no such linking is done. The default value for the 
   parameter is GEOMETRY.
