[Ndn-interest] How to add the SecRuleRelative Rules in validator-regex?

Hi,

I'm trying to use the validator-regex to validate the incoming data, but I
stuck at how to add the SecRuleRelative Rule.

Can somebody tell me some clues?

Specifically, I find the example in SecurityLibrary(
http://redmine.named-data.net/projects/ndn-cxx/wiki/SecurityLibrary), but I
don't understand the RuleRelative rule below ...

SecRuleRelative rule("^(<>*)$", "^([^<KEY>]*)<KEY>(<>*)<ksk-.*><ID-CERT>$",
                     ">", "\\1", "\\1\\2", true);

What's the meaning of ">", "\\1", "\\1\\2" ? Can someone give me an example?

Thanks,

Chengyu
