Re: Aligning grouping of resources in POWDER and WAF Access Control.

We took the view that, with few exceptions, if you own example.com, you 
have complete control over example.example.com too.

It means that, in the POWDER world, you could publish a description of 
"com" - i.e. everything on .com. It may be pretty meaningless, but, 
well, when did language stop people saying meaningless things? :-)

It's tempting to try and add restrictions such as requiring at least a 
2nd level domain. This might have the desired effect for .com, .org etc, 
but falls down in places where third level domains are the norm (.co.uk, 
.com.au, .com.cn etc.)
