== sources or references == 

 This article IS all citation from the ICBN, which is mentioned as its source in line 1. The different articles are cited for the different statements. I also think there is no better source to cite than the Code, as the meaning, use and priority of the concept are defined and regulated there. 

 Not having a  section does not mean that no sources are cited. Based upon the above, the tag "this article does not cite any references or sources" was applied without care. I therefore removed it. -
