Arguments
   PERFORM_OPERATION
      Keyword indicating that function is used to perform <caseType> operation. This
      used to be the default when there were 3 arguments. Now that we need to pass
      the extra <whiteSpaceChars> option we have to improvise to indicate in which
      mode the function is being used.
   ATTR_LIST_DEF_VAL
      Transformer keyword indicating that the parameters give a set of source attributes
      to rename, their destination name and a default value to use should the source attribute
      not be found on the feature.
  
  ATTR_LIST_DEF_VAL_ENCODED
      Same as ATTR_LIST_DEF_VAL except each item in the triplet (<source>,<target>,<defValue>)
      is FMEParsableText encoded.

   <change_attr_opt>   
      The part of the attribute to be changed. Choices are Name, Value or Both.
      
      Range: name | value | name_val
      
   <regexp>   
      Either the name of the source attribute to change or a regular expression 
      that is used to parse through the set of attribute names and select the 
      ones that need changing.
      
      Range: String
      
   <caseType>   
      The case type to change the selected attribute names and/or values to. 
      Choices are UPPERCASE, lowercase, Title case, and Full Title Case.
      
      Range: upper | lower | title | fulltitle

  <whiteSpaceChars> (optional, defaults to "-")
      List of characters (in addition to space) that are used as word 
      delimiters when performing title or fulltitle case conversion operation

   <default value>
      The default value to use when renaming. If the source attribute is not found
      the destination attribute will be created using this default value.

   <targetAttributeName>   
      Target attribute name after change.
      
      Range: String
      
   <sourceAttributeName>   
      Source attribute name prior to change.
      
      Range: String
      
   LIST_ATTR   
      Transformer keyword indicating that the next argument is <attr_list> and 
      not <regexp>.
      
      Range: N/A
      
   PATTERN_REPLACE   
      Transformer keyword indicating to rename attributes based on a pattern.
      
      Range: N/A
   
   <patternAction>   
      The action to perform when renaming the attributes.
      
      Range: ADDPREFIX | ADDSUFFIX | REMOVEPREFIX | REMOVESUFFIX | REGEXPREPLACE |
             STRINGREPLACE
      
   <caseSensitive>      
      Whether or not the pattern rename should be case sensitive.
      
      Range: YES | NO
      
   <replacePattern>   
      The FMEParsableText encoded pattern to replace. This is only used if REGEXPREPLACE or 
      STRINGREPLACE is specified as the <patternAction>.
      
      Range: String
      
   <replaceString>   
      The FMEParsableText encoded string that should be inserted or removed from the 
      attribute name.
      
      Range: String
      
   <attr_list>  
      The list of attributes that should be affected by the rename. If no 
      attributes are specified, all attributes will be renamed.
      
      Range: Space Delimited Encoded String

   FME_STRICT
      Transformer keyword indicating that if source attribute does not exist,
      target attribute will not be created.

      Range: N/A
      
Description

   There are five ways to use this function:
   
   1. Specify the part of the attribute (name, value or both) that is to be 
   changed, the regular expression to be used to select those attributes to 
   change, and the case type to change to. The regular expression will parse 
   based on attribute names only.  This use does not currently support
   feature tables.
   
   2. Specify the target and the source attribute names.  This mode supports
   feature tables.
   
   3. Using the CaseChanger transformer, select those attributes to be changed 
   from the list, and which case to change them to.  This use does not currently support
   feature tables.
   
   4. Using the AttributeExpressionRenamer to rename attributes based on a 
   pattern.  This use does not currently support
   feature tables.
   
   5. Rename attributes, and use a default values for source attributes that don't exist.
   This method supports feature tables.

   If there is no specific encoding type associated with the attribute, it is 
   assumed to be in system encoding.
