<limit> Information still accurate?

[ChicagoFaucet]

I'm currently having issues with vehicles spawning on my server via events that I created. So, I'm troubleshooting that right now. On the Nitrado messageboards, I came across this explanation about the <limit> entry for events. Does anyone know if this is still accurate? Any additional information would be appreciated.

There are 4 modes for events, Child, Parent, Mixed & Custom.

1. Parent, at each event location you would find all child items listed.
2. Child, at each event you would always find 1 random child type, ignoring child min/max values.
3. Mixed, at each event you would find 1 random item, limited by its child's min/max values.
4. Custom, uses external XML file like territories.xml for numbers and locations.
