would be to either have the first line of the file being something like 
[PUA00001] or to have the file name be something like MYFILE.TXTPUA00001.  
Where "PUA00001" equals the CSUR.  Other numbers (PUA00002, PUA00003, etc.) for 
other PUA conventions.

The problem that then arises is that a registry is needed for what those 
numbers mean, such as PUA01728. So what if someone writes explaining his 
designs for glyphs for the language of the people who live in the northern part 
of the fifth planet from the sun in the science fiction novel he is writing? Is 
registration granted instantly upon request or is there a threshold of some 
sort? What if lots of people do that, including some people wanting a registry 
code number for the various emoji that they want? If there is a threshold of 
proving usage and so on, or of showing that the designs have been produced AT a 
business or AT a college or whatever, then the system will only work for some 
users of the Private Use Areas.

My opinion is that the system needs to be free-standing, with each usage 
possibly self-contained or with an external reference to a document that is 
available. Care would need to be taken to send a copy of any such document to 
deposit libraries such as The British Library so as to ensure long-term 
conservation.
