0035  * ber_tag_t represents the identifier octets at the beginning of BER
0036  * elements.  OpenLDAP treats them as mere big-endian unsigned integers.
0037  *
0038  * Actually the BER identifier octets look like this:
0039  *
0040  *  Bits of 1st octet:
0041  *  ______
0042  *  8 7 | CLASS
0043  *  0 0 = UNIVERSAL
0044  *  0 1 = APPLICATION
0045  *  1 0 = CONTEXT-SPECIFIC
0046  *  1 1 = PRIVATE
0047  *      _____
0048  *      | 6 | DATA-TYPE
0049  *        0 = PRIMITIVE
0050  *        1 = CONSTRUCTED
0051  *          ___________
0052  *          | 5 ... 1 | TAG-NUMBER
0053  *
0054  *  For ASN.1 tag numbers >= 0x1F, TAG-NUMBER above is 0x1F and the next
0055  *  BER octets contain the actual ASN.1 tag number:  Big-endian, base
0056  *  128, 8.bit = 1 in all but the last octet, minimum number of octets.
