/* A Presentation Element (or PElement) is an internal representation for
a presentation type from ISO8825. The fields of the structure are:
pe_class: UNIVersal, APPLication, CONText, or PRIVate
pe_form: PRIMative, CONStructor, InlineCONStructor
pe_id: identifier
pe_len: if a PRIMative, then the length of pe_prim,
else a scratch value; "indefinite" length elements
have a pe_len of -1 (PE_LEN_INDF)
pe_ilen: if an InlineCONStructor, then the offset to the real
data portion
pe_prim: if a PRIMative or an Inline CONStructor, the
byte-string
pe_cons: if a CONStructor, the first element in the
singly-linked list of elements
pe_next: if the immediate parent is a constructor, the
next element in the singly-linked list of elements
pe_cardinal: if a LIST (SET or SEQ CONStructor), the cardinality
of the list
pe_offset: if a member of a SEQ LIST, the offset in the SEQUENCE
pe_nbits: if a BITSTRING, the number of bits in the string
pe_refcnt: a hack for ANYs in pepy
