Notes of the table format

• The ALIGN=CENTER VALIGN=TOP for every row is redundant : you can set that up in the table header.
• The non-breaking spaces could be avoided by disabling word wrap : the "Meaning" field should have rather short lines.
• If you need to expand on a field's meaning, you can always put extra documentation (sorta footnote) below the table

(paragraphs, formulas, mini-tables, etc).

• Alternatively, the generic row can be a set template, with no-wrapping specified only for columns 3 and 4
• you'd call it with something like {{OBD Table Row| 0x00 | File ID | FF0000 | 01 '''51 02''' 00 | 593 | 00593-.ABNA }}

Yeah, I know, this should go in the talk page. We'll delete it later anyway. For now let's use ABNA as a sandbox/battlefield ^^

Unknown (last two)

Hm, these are almost certainly links to other nodes (it's a tree, heh).

Extreme values of unknown fields (especially integers) are quite useful.

Could you systematically provide them when they're available?

Plane equation link

Beats me right now, but a look at the child nodes will surely help. Investigating ASAP...

Should be something like a separating plane that makes the engine choose one child or the other.

Probably axis-aligned.

Gunk quad link

Ditto (beats me, investigating ASAP)

BSP

What does BSP stand for, anyway?
