-  The internal implementation of *_DECOMPRESS_PROTOCOL.Decompress().

-  @param Source          - The source buffer containing the compressed data.
-  @param Destination     - The destination buffer to store the decompressed data
-  @param Scratch         - The buffer used internally by the decompress routine. This  buffer is needed to store intermediate data.
+  Decompresses a Lzma compressed source buffer.
+
+  Extracts decompressed data to its original form.
+  If the compressed source data specified by Source is successfully decompressed 
+  into Destination, then RETURN_SUCCESS is returned.  If the compressed source data 
+  specified by Source is not in a valid compressed data format,
+  then RETURN_INVALID_PARAMETER is returned.
 
-  @retval RETURN_SUCCESS           - Decompression is successfull
-  @retval RETURN_INVALID_PARAMETER - The source data is corrupted  
+  @param  Source      The source buffer containing the compressed data.
+  @param  SourceSize  The size of source buffer.
+  @param  Destination The destination buffer to store the decompressed data
+  @param  Scratch     A temporary scratch buffer that is used to perform the decompression.
+                      This is an optional parameter that may be NULL if the 
+                      required scratch buffer size is 0.

+  @retval  RETURN_SUCCESS Decompression completed successfully, and
