Would there be any interest in a tag like "locked=yes" for nodes which 
shouldn't be changed?

* Similar to write-protection on a file, or the write-protect switch on a 
diskette or tape: prevents *accidental* moving/destruction of something 

* GUI editors might refuse to move or delete a node with that tag, unless 
someone first removes the tag 

* Watchlists (when/if implemented) might attach special importance when a 
"locked" node is moved
