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.
