OMR File Header

[Johann Eisner]

Hello Everyone

After reading the OMR file Specification the nineteeth time, I am a little confused:
Under File Header is this written:

File Headers

Each individual model file in the MPD that does not represent an unofficial part must have the following standard header format.
Standard Header:

Code:

0 FILE <Filename>.ldr
0 <Individual filename>
0 Name: <Filename>.ldr
0 Author: <Author Name> [Username]
0 !LDRAW_ORG Model -OR- 0 !LDRAW_ORG Unofficial_Model
0 !LICENSE Redistributable under CCAL version 2.0 : see CAreadme.txt

and under OMR example this:

OMR Example

Code:

0 FILE 6712 - Main.ldr
0 Main
0 Name: 6712 - Main.ldr
0 Author: Willy Tschager [Holly-Wood]
0 !LICENSE Redistributable under CCAL version 2.0 : see CAreadme.txt

Now the question:
Ist the line "0 !LDRAW_ORG Model -OR- 0 !LDRAW_ORG Unofficial_Model" nessacery or not?
