+  Produces a Null-terminated Unicode string in an output buffer based on 
+  a Null-terminated Unicode format string and a VA_LIST argument list
+  
+  Produces a Null-terminated Unicode string in the output buffer specified by StartOfBuffer
+  and BufferSize.  
+  The Unicode string is produced by parsing the format string specified by FormatString.  
+  Arguments are pulled from the variable argument list specified by Marker based on the 
+  contents of the format string.  
+  The number of Unicode characters in the produced output buffer is returned not including
+  the Null-terminator.
+  If BufferSize is 0 or 1, then no output buffer is produced and 0 is returned.
+
+  If BufferSize > 1 and StartOfBuffer is NULL, then ASSERT().
+  If BufferSize > 1 and StartOfBuffer is not aligned on a 16-bit boundary, then ASSERT().
+  If BufferSize > 1 and FormatString is NULL, then ASSERT().
+  If BufferSize > 1 and FormatString is not aligned on a 16-bit boundary, then ASSERT().
+  If PcdMaximumUnicodeStringLength is not zero, and FormatString contains more than 
+  PcdMaximumUnicodeStringLength Unicode characters not including the Null-terminator, then
+  ASSERT().
+  If PcdMaximumUnicodeStringLength is not zero, and produced Null-terminated Unicode string
+  contains more than PcdMaximumUnicodeStringLength Unicode characters not including the
+  Null-terminator, then ASSERT().
+
+  @param  StartOfBuffer   A pointer to the output buffer for the produced Null-terminated 
+                          Unicode string.
+  @param  BufferSize      The size, in bytes, of the output buffer specified by StartOfBuffer.
+  @param  FormatString    Null-terminated Unicode format string.
+  @param  Marker          VA_LIST marker for the variable argument list.
+  
+  @return The number of Unicode characters in the produced output buffer not including the
+          Null-terminator.
