/*
* ber_tag_t represents the identifier octets at the beginning of BER
* elements. OpenLDAP treats them as mere big-endian unsigned integers.
*
* Actually the BER identifier octets look like this:
*
* Bits of 1st octet:
* ______
* 8 7 | CLASS
* 0 0 = UNIVERSAL
* 0 1 = APPLICATION
* 1 0 = CONTEXT-SPECIFIC
* 1 1 = PRIVATE
* _____
* | 6 | DATA-TYPE
* 0 = PRIMITIVE
* 1 = CONSTRUCTED
* ___________
* | 5 ... 1 | TAG-NUMBER
*
* For ASN.1 tag numbers >= 0x1F, TAG-NUMBER above is 0x1F and the next
* BER octets contain the actual ASN.1 tag number: Big-endian, base
* 128, 8.bit = 1 in all but the last octet, minimum number of octets.
