     - when encoding the length field for a structured type, i.e., a
       SEQUENCE or SEQUENCE OF, the indefinite form encoding is
       permitted.

   For example, the file containing the data:

   [1] IMPLICIT SEQUENCE     a1 80
         OCTET STRING        04 09 73 77 69 74 63 68 2d 31 32

               INTEGER                02 01 21

   contains two connection records, each containing one tuple listing
   two (integer) data items in a (fictitious) subtree:
   1.3.6.1.3.127.1.1.  Its header indicates it's for "switch-12", with
   description "Accounting", and was collected at 16:05:00 on 20 July
   1996.

   As well as the standard format defined above, the MIB allows other
   enterprise-specific formats to be used.

    DESCRIPTION
            "The list component of a (subtree, list) tuple.  Such a
            (subtree, list) tuple defines a set of objects and their
            values to be collected as accounting data for a connection.
            The subtree specifies a single OBJECT IDENTIFIER value such
            that each object in the set is named by the subtree value
            appended with a single additional sub-identifier.  The list
            specifies a set of data items, where the presence of an item
            in the list indicates that the item is (to be) present in
            the data collected for a connection; the absence of an item
            from the list indicates that the item is not (to be) present
            in the data collected for a connection.  Each data item is
            represented by an integer which when appended (as as
            additional sub-identifier) to the OBJECT IDENTIFIER value of
            the subtree identified by the tuple, is the name of an
            object defining that data item (its description and its
            syntax).

            The list is specified as an OCTET STRING in which each data
            item is represented by a single bit, where data items 1
            through 8 are represented by the bits in the first octet,
            data items 9 through 16 by the bits in the second octet,
            etc.  In each octet, the lowest numbered data item is
            represented by the most significant bit, and the highest
            numbered data item by the least significant bit.  A data
            item is present in the list when its bit is set, and absent
            when its bit is reset.  If the length of an OCTET STRING
            value is too short to represent one or more data items
            defined in a subtree, then those data items are absent from
            the set identified by the tuple of that subtree and that
            OCTET STRING value."
