RTC4.0 Enterprise Extension dependency build: What is the "dependency type?"

I am setting up a dependency build environment for IBM i with RTC4.0.6 and would like to ask for help.
When creating a language definition, the manual said to add "dependency types" in the "scanner" tab but I don't know what these are and I don't know how this relates to other settings. I searched for more detailed descriptions of "dependency types" but did not find any in the manual nor on jazz.net.
So could anyone kindly tell me about "dependency types?" Do I have to create my own "dependency type/s?" If so, can you also please help me how make one? Or are they already provided with the RTC4.0?

Hi,
There is no need to create your own dependency types, each supplied scanner comes configured with its own set of supported dependency types.
When a scanner is first associated to a Language Definition all of its supported dependency types are automatically added to the (editable) dependency type table. As illustrated here:
