 // This class manages the WebIntents table within the SQLite database passed
 // to the constructor. It expects the following schema:
 //
 // web_intents
 //    service_url       URL for service invocation.
 //    action            Name of action provided by the service.
 //    type              MIME type of data accepted by the service.
+//    title             Title for the service page
+//    disposition       Either 'window' or 'inline' disposition.
 //
-// Intents are uniquely identified by the <service_url,action,type> tuple.
+// Web Intent Services are uniquely identified by the <service_url,action,type>
+// tuple.
+//
+// Also manages the defaults table:
+//
+// web_intents_defaults
+//    action            Intent action for this default.
+//    type              Intent type for this default.
+//    url_prefix        URL prefix for which the default is invoked.
+//    user_date         Epoch time when the user made this default.
+//    suppression       Set if the default is (temporarily) suppressed.
+//    service_url       The URL of a service in the web_intents table.
+//    extension_url     The URL for an extension handling intents.
+//
+// The defaults are scoped by action, then type, then url prefix.
