Being able to differentiate better vetted sources _within_ the well- known domain restores a level of trust when messages are both signed by the well-known domain, and also marked as restricted (either transactional or administrative). This assumes the well-known domain protects this trust by limiting access to these special keys (denoted by special selectors). The well known service provider or institution could have their administrative or transactional messages obtain a trust annotation, without fearing one of their millions of customers or less trustworthy employees will spoof other customers by sending a hazardous message asking to apply a browser plug-in, for example.

Why would this need standardization? All a domain needs to do is decide for
itself which selector subdomains to organize the different kinds of traffic it
views as, well, different, and reputation systems ought to be able to figure this
out for themselves. Indeed, they MUST be able to independently establish
that.
