What would that be?

[YAKO SOMEDAKY]

What would this information be that I got by viewing my campaign's db.xml?

This is just an excerpt from the db, focused on showing these "names"
<toggleable /> | <single_sided /> | <counterclockwise />

I am especially curious to know what this is <single_sided />


<occluder>
<id>1</id>
<points>2472.9,-2601.5,2689.3,-2601.5,2689.3,-2394.1,2472.9,-2394.1</points>
<toggleable />
<hidden />
<single_sided />
<terrain />
<allow_move />
<closed />
<counterclockwise />
</occluder>

It is a terrain occluder.

Toggleable means that it can be switched on or off, not sure about the other two.

I imagine that <single-sided /> will be a means of directing occlusion?
If so, I will love that possibility!

If you mean that it blocks LoS from one side and not the other - then that's not the case. A terrain occluder blocks LoS from one side until you enter it and then you can see out in all directions. Once you leave it again then it blocks LoS back the way you came out.
