Compound SFI

A compound SFI includes multiple values each with own data type and length.

Compound type:

1: Factored. A Binary(8) value combined with a second field containing a count. The second field is identified by a data type.

Factor values:

and so on.

Compound SFIs follow this structure;

Byte Count: Description
8: Standard SFI including 1 byte data type identifier (X'08')
1: Compound type identifier; 1 = Factored; 2 self describing fields where the first is the factor used, and the second is the resultant value
1: Length of the first field, including this byte
1: Data type identifier
n: First data field as identified by the preceding data type field; for example Binary(8)
1: Length of the next field, including this byte
1: Data type identifier
n: Next data field as identified by the preceding data type field; for example Binary(64)
