==Process==
First released in 2012, the process for developing RZ-LGR currently follows the [https://www.icann.org/en/system/files/files/draft-lgr-procedure-20mar13-en.pdf Procedure to Develop and Maintain the Label Generation Rules for the Root Zone in Respect of IDNA Labels], last updated in 2013. Broadly speaking, Step #, a [[Generation Panel]] makes a broad set of code points for the relevant script, called the "Maximal Starting Repertoire," and proposes Label Generation Rules. Step #, the team's proposal is reviewed by the [[ICANN Community]] through [[Public Comment]] and then by the [[Integration Panel]] for approval and integration into the LGR for the [[Root Zone]].
