Actually, if you look in the definition of "Content", you'll find:

"The content of an element may include text, and it may include a number of
sub-elements, in which case the element is called the parent of those
sub-elements."

> Child - An element A is called the child of element B if an only if B is
the

> Descendant - An element A is called a descendant of an element B, if
either
> (1) A is a child of B, or (2) A is the child of some element C that is a
> descendant of B.

At first it appears to be what these definitions result in, but if we parse
this step by step, we find that in fact Jacob is also a descendant of Fred.
Like this:

- Jim and Jane are children of Fred, and so by part (1) of the definition of
"descendant", are descendants of Fred.
- Jason, Justine and Jeff are children of Jane, who we have parsed as being
a descendant of Fred, and so by part (2) of the definition of "descendant",
these three are also descendants of Fred.
- Jacob is a child of Justine, who we have parsed as being a descendant of
Fred, and so by part (2) of the definition of "descendant", Jacob is also a
descendant of Fred.

As far as I can see, the "descendant" definition means that any element
which can be linked through a direct series of child to parent relationships
back to an element A is a descendent of element A.
