For purposes of enhancement, will an out of state conviction for assaulting a family member satisfy the requirement under 22.01(b)(2)of the Penal Code to get the punishment from a class A misd. to a state jail felony? What implication does "under this section" have if any?

Isn't that covered in The Perfect Plea?

Although Mr. Bradley covered a vast array of topics in his book, assault family violence enhancement is not covered to my knowledge.

Then, you might try watching CSI. Perhaps they have an episode on point.

Or you can check this thread for the answer (which is no, but will soon be yes):
