I have one concern: that what it would do is cancel the definition of a spouse. For the intention that you are presenting now, I'm not sure that would be the way to do it, because the definition of a veteran has been modified, and to make it consistent, instead of going from paragraph (a) to (e) you could go from paragraph (a) to (f), and that would include all the definitions.
What this amendment would do right now, I think, is simply abolish the definition of a survivor, which would create difficulties, obviously.
