I think Benno provided some examples, but to use a dead-simple one  
from OOSTethys, I grabbed more or less at random one of the XML  
description files, that had the snippet below at its top. The xlink is  
in the 4th to last line, and simply 'tags' the sml:member element with  
a unique ID pointing to the instance. While this ID was a URN, it  
could just have easily been a URL that resolved to a file or a sensor  
description.

I think we have many other examples but they would be harder for me to  
find, sorry.
