No, there's no such formal description, AFAIK.

Informally, it's like a filename in TeX, except that if the scanner  
encounters a 'single quote' or "double quote" character, it will  
accept spaces as part of the name until it finds the matching  
character to close the quoted part of the name. Such quote marks are  
not themselves part of the name. (To include a quote mark in the  
name, it should be within a section that is quoted using the other  
variety of marks.)
