-// Representation of a condition in the Declarative WebRequest API. A condition
-// consists of several attributes. Each of these attributes needs to be
-// fulfilled in order for the condition to be fulfilled.
-//
-// We distinguish between two types of conditions:
-// - URL Matcher conditions are conditions that test the URL of a request.
-//   These are treated separately because we use a URLMatcher to efficiently
-//   test many of these conditions in parallel by using some advanced
-//   data structures. The URLMatcher tells us if all URL Matcher conditions
-//   are fulfilled for a WebRequestCondition.
-// - All other conditions are represented as WebRequestConditionAttributes.
-//   These conditions are probed linearly (only if the URL Matcher found a hit).
-//
-// TODO(battre) Consider making the URLMatcher an owner of the
-// URLMatcherConditionSet and only pass a pointer to URLMatcherConditionSet
-// in url_matcher_condition_set(). This saves some copying in
-// WebRequestConditionSet::GetURLMatcherConditionSets.
