Doubt in FSM extraction!.

Doubt in using attribute for FSM extraction!.

Hello friends!, I have a little doubt regarding FSM usage via "Attributes" in xilinx ISE environment. Using attribute functions we can specify the FSM extraction attribute such as "FSM_Encoding" for encoding a signal for "One-hot", "gray", etc. But what does this attribute "ENUM_ENCODING" is used for?.You are just specifying the states of your own, but such best states are already packed with the tool..Does this attibute function have anything different than the other one?...Xilinx already has all FSM encoding styles inbuilt. But what is the necessity for this attribute "ENUM_ENCODING" other than user's own specification?....Thanks for your time guys....

I found this article here:
**broken link removed**

so enum_coding is used when the fsm_encoding is set in "user" mode.So we can set the encoding type.
