Attached files and screen shots give examples, here is a summary
base mxml defined this way

<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"
xmlns="common.securitygateway.components.*" xmlns:component="common.components.*"
initialize="init()">

and it is extended using the following syntax (note this is working code)
<SG:LoginMain xmlns:mx="http://www.adobe.com/2006/mxml"
xmlns:SG="common.securitygateway.components.*"
xmlns:view="views.*" initialize="init()"
appName="Ebt" mainLoginSuccess="handleLoginSuccess(event)"
sessionLogOff="forceLogOff(event)">

inspection incorreclty flags the following as issues
private function doRegisterUser(evt:Event):void {
super.switchView('loginRegistration'); — inspection flags switchView as unknown but it is public in subclass
}

registerLink = myRegisterLink; – inspection flasgs registerLink as unknown but it is public function set in subclass

dispatchEvent(new CommonEvent("loginSuccess")); – inspection flags dispatchEvent as unkown

• subclass's attributes unknown

label = "Log-in"; – inspection reports label as uknown but it is an attribute of the extended Canvas component

AGAIN please not this is working code, not theory, extending MXML is very useful concept
