5.1.1. Mapping to the SYNTAX clause

When mapping to the SYNTAX clause of the OBJECT-type macro:

1. An object with BOOLEAN syntax becomes an INTEGER taking either of values true(1) or false(2).

2. An object with ENUMERATED syntax becomes an INTEGER, taking any of the values given.

3. An object with BIT STRING syntax containing no more than 32 bits becomes an INTEGER defined as a sum; otherwise if more than 32 bits are present, the object becomes an OCTET STRING, with the bits numbered from left-to-right, in which the least significant bits of the last octet may be "reserved for future use".

4. An object with a character string syntax becomes either an OCTET STRING or a DisplayString, depending on the repertoire of the character string.

5. An non-tabular object with a complex syntax, such as REAL or EXTERNAL, must be decomposed, usually into an OCTET STRING (if sensible). As a rule, any object with a complicated syntax should be avoided.

6. Tabular objects must be decomposed into rows of columnar objects.
