Yes...I got rid of the names because they seemed easy to confuse:
there's a difference between the v-bit and the V-bit.  I can add a
short description to each Encapsulation Type:

+=====+=================================+===========================+
| Bit | Encapsulation Type              | Reference                 |
+=====+=================================+===========================+
| 0   | No Encapsulation (n-bit)        | [[this RFC],Section 4.15] |
+-----+---------------------------------+---------------------------+
...
+-----+---------------------------------+---------------------------+
| 26  | Geneve (G-bit)                  | [RFC8926]                 |
+-----+---------------------------------+---------------------------+
| 27  | NV-GRE (N-bit)                  | [RFC7637]                 |
+-----+---------------------------------+---------------------------+
...

...and then include the drawing:

 0                   1                   2                   3
 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|n|                   Encapsulations              |U|G|N|v|V|l|L|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+



...OR...

I can add text to describe the bit positions: "The Bits correspond to
the positions in the following drawing:".

 0                   1                   2                   3
 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|                         Encapsulations                        |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Thanks!
