Note that the implementation of the target features is in a separate library (not libomp), 
therefore they should be documented in a separate document; both because that library
can also be used without libomp (in which case a single document makes things hard to find
for people who want to do that), and because it becomes mechanistically hard to run
doxygen across the two libraries!

There's a PDF you can find here:

We should probably make sure that the most up-to-date document is in the 
repository.

Yes.
