There is a registry of URN namespace ids (NIDs). Anyone inventing a  
new one would be advised to check for collisions, and then apply to  
IANA following documented procedure. Failure to do so is as much a  
violation of internet naming rules as invention of a colliding URI  
scheme or top-level DNS domain would be.

(I know I've seen an unofficial list of NIDs - including numerous  
unregistered NIDs - but can't find it now)

Oddly, urn:lsid: is not registered with IANA.
