Children: References vs. Canonical Relations

startec's icon

In the live object model, in the upper right there is a chart that says "Children, references vs. canonical relations"  I attached a picture of the chart and I just not sure what the difference is, or what exactly those routes mean.  What, for instance, is an unspecified canonical relation? Or what is a "list" reference.   I am not sure what the significance of those things are. Can anyone clarify? Thanks
