*The "WindowType" is the window type of the chrome. Possible values are "navigator", "messenger", etc. The "ProviderType" is one of the four providers: content, skin, platform, or locale. Examples of the provider names, "ProviderName", are Mozilla, Mozillazine, xyzOrg, myISP, and etc. (Refer to [http://www.mozilla.org/projects/intl/iuc15/paper/iuc15xul.html XUL - Creating Localizable XML GUI] for illustrations).
