It is the area in the area tree below which (as a parent of) an area 
generated by the interpretation of a formatting object is placed.

Not quite ... out-of-line areas generated by a formatting object found in 
the object tree will be positioned elsewhere in the area tree than 
inline-areas.

There are many trees in play ... check the diagram on page 45 of the free 
preview of our XSL-FO book (the preview includes the full text of the first 
three chapters).  The instance tree, FO tree and Refined FO tree have 
parent, children and sibling objects.  The area tree has parent, children 
and sibling areas.

I hope this helps.
