Today, it is thought that a black hole's gravity is too strong for light to escape, but at the same time x-ray radiation does escape from black holes. Given that light is one weaker form of radiation, that seems to be a contradiction of our knowledge of gravity.
Do we need to a adjust our understanding to be that black holes do not produce any light because the high gravity beyond the event horizon has changed the electron vs the nucleous ratio. Light is no longer be produced. It is not that gravity is able to hold it.
X-ray radition is produced from the tremendous energies within the black hole's destruction of each atom's neucleous. That is Einstein. The electrons from these atom's have already been stripped from the atom. The electron's that produce light were stripped at the event horizon. Therefore, no more light production within the black hole.

The only theory that supports the emission of anything from black holes is Hawking theory, and it's thermal radiation, not X-rays. X-ray jets are emitted from the area outside the event horizon in the accretion disk. Read the article below for what actually comes out fo the whole and at what rate.

Quantum theory already explains this radiation. holden has already beaten me to the punch, it would seem, with the introduction of the Hawking theories on black holes, but I will simplify from what I have read of these theories.
Quantum particles come in pairs. They are bound to one another with certain quantum packets of "information", for lack of a better, simpler term. There is a small chance that a quanta may "escape" the event horizon of a BH, which Hawking explains with his Evaporation theory. This chance, while small, is spread amongst the enormous amount of quantum packets within a BH. Think of it as the same as the chance that the Boston Red Sox would come back from a 3-0 deficit in the World Series. While small, they showed that with enough data, even the smallest percentage can happen ;P
But I digress...Hawkings work, as well as Kaku and others studying BH Theory has given us windows into the radiation "leaks" around BHs. Our understanding has already been adjusted.

The claim that we understand black holes needs to be adjusted. We have some theories, and we try to calculate consequences of those theories and compare them with the extremely limited data we have, and see if they match. It's like using binoculars to watch a baseball game 3000 miles away.
