I don't know org-dp myself, but Thorsten posts here regularly.

But all elements contain :begin and :end and most :contens-begin
and :contents-end (maybe sans an 's').

Maybe it would be easier if you state plainly what your desired goal is?
It's all a bit abstract. You can write pretty sophisticated things using
just (org-element-at-point) (e.g. I have a function that escapes
*math-su{b,per}script* on double space at appropriate places).

If you want to manipulate the buffer text use the great functions. You
can condition on the element under point or whatever you desire and then
use the regular functions you'd otherwise use. I'm probably wrong, but it
seems as if you trying to shoot flies with canons, or however the saying
goes in English. Also, recall there is no such thing as wrong Org-syntax
(but there is unexpected outcomes).
Check Org.el if you want.
Cheers,
Rasmus
