Oh - and how could I forget - from the most canonical definition of
the property there is:

" a description is intended to provide more verbose information …
Include ID references to multiple elements if necessary, or enclose a
set of elements (e.g., paragraphs) with the element referenced by the
ID."

http://www.w3.org/WAI/PF/aria/states_and_properties#aria-describedby

Not only mere multiple _sentences_ but multiple _paragraphs_!
