I don't like this example. As I see it the natural interpretation of 
this construct is that the e-mail address is 
fred@somewhere.com2005-02-02. I don't think this is a good use of a 
mixed content. I would write this construct as:


Here what's needed is better support for sibling elements.

A better example might be:


Here the username element contains exactly and only the username; the 
host element contains exactly and only the host; and the email element 
contains exactly and only the email address.

This would be even more compelling with street addresses, where many 
different unplanned things can show up as part of the address in a 
different country, and where the boundary whitespace might be used to 
format the address when printed on an envelope.
