small nit in draft-ietf-rmt-bb-lct-revised-04

The text in section 5.2.1 says that

"There are two formats for Header Extension fields, as depicted in 
Figure 2.  The first format is used for variable-length extensions, with 
Header Extension Type (HET) values between 0 and 127.  The second format 
is used for fixed length (one 32-bit word) extensions, using HET values 
from _127_ to 255."

The diagram in Figure 2 designates values from 128 (not 127) to 255 for 
fixed length extensions. I believe the diagram is correct.

Thank you,
