[ASN.1] SET OF encoded with length=0

[Norbert van Bolhuis]

Is it allowed to encode (BER) a SET OF
with length_byte=0 ?
So, for example:

300a80065678901234563100

  Class      =CLASS_UNIVERSAL
  Constructed
  Type       =SEQUENCE,SEQUENCE_OF
  Length     =10
  {
    Class      =CLASS_CONTEXT_SPECIFIC
    Type       =NONE_0
    Length     =6
    Val        =0x567890123456
    Translated =567890123456
    Class      =CLASS_UNIVERSAL
    Constructed
    Type       =SET,SET_OF
    Length     =0
  }
