You can squat the namespace, however since one expects a definition of 
the terms at http://xmlns.com/foaf/0.1/ you cannot control the meaning 
of the terms.

You can add any property to a foaf:Person, I'd suggest you to define 
these properties on a web-page you control. With this you can make the 
schema available to the search engine, you could e.g. define a property 
foaf-ex:mobilePhone to be a subProperty of foaf:phone this would allow a 
search engine to partially understand the meaning event if it didn't 
know about foaf-ex before.

It is in most cases it is in the interest of application developers to 
use terms that are widely understood.

It's a bit similar to natural language, you've choosen to write your 
mail in english evenn if their is governing body enforcing you too.


cheers,
