   I.e. we use the notation for byte string representations as specified by the python programming language.
-  We do so for clearly
-  distinguishing octet string representations from places where quotation marks correspond to normal language use (e.g. for citations of definitions from other standard documents).

 - prepend\_len(octet\_string) denotes the octet sequence that is obtained from prepending
   the length of the octet string to the string itself. The length shall be prepended by using an LEB128 encoding of the length.
