 SHOULD be made of alphanumerical chars
 the exact values are outside of the scope this spec
 if a codec specifies a prefered identifer which fits within the
 constraints of this syntax element then it SHOULD be used, if a codec
 is commonly using a identifer which fits within the constraints of this
 syntax element in another container format then that identifer SHOULD be
 used
 if there are several possible values to choose from then the one used
 in the source file if any SHOULD be prefered, if there are still several
 options left then the one with the most descriptive name SHOULD be
 preferred
