For XML resources this could be done using xpointer in the URI fragment.

What is the domain here? www.helloworld.net? helloworld.net? net?

www2.helloworldagain.net and www3.helloworldagain.net are not subdomains 
of www.helloworldagain.net. However they are subdomains of 
helloworldagain.net.

You mean, this is an issue with exclusions?

AFAIR, there should be a way to compress statements in an EARL report, 
so that not every resource/web unit has to be listed explicitly. This 
compression is most likely not lossless. I very much doubt that we can 
create a lossless compression. There are too many parameters. And what 
would be the benefit? If we wanted to know whether a specific resource 
is part of the subject of the compressed statement, we would have to run 
a crawler with all the specified parameters first? Hmm
