yes, unless you have time to do a security editor

when a component wants to see if it can do something, it does as is : core.secAuthAction("html::", fileId + "::", Level.READ);
the security code will also traverse all the rules filtered by the user group ID to retain only the rules related to that user.
for each rule, the component pattern is first matched, if it match then it will try to match the instance pattern. if this is ok it will return true if the level in the rule is lesser or equal than the level given as parameter.

yes exactly, these are regular expressions and are a mean to exprimate security, it could be done differently.

yes, but their implementation is crap and ambigous, however the principles are the same.
