A user asked this about the cfajaxproxy tag:

Any way around CFAJAXProxy exposing all remote component functions to JavaScript? To elaborate, I have a component with x remote functions. A particular page call requires only one of these remote functions. I’d like CFAJAXproxy to expose only the required functions.

He also tried cfcontent:

Earlier today I did a code maintenance session on BlogEngine.NET using the excellent FxCop tool.

It’s been a while since I have so there were quite a few things to correct in the code. I actually like spending time with FxCop and fixing the broken rules. There’s something very relaxing about it. Even though FxCop is excellent, it is not without its quirks.
