NOTE Refer to the “FTAM Data Structures” chapter for detailed information on

setting the FTAM-3 document type using the Ft_dt_ftam_3 structure.

FTAM-3 Document Semantics

The following semantics are mandatory for FTAM-3 document types.

• FTAM-3 uses the constraints speciﬁed by the Unstructured

constraint set.

• FTAM-3 does not specify the semantics of the binary strings.

• Each binary string contains octets of any value from 0 to 255.

FTAM-3 does not constrain the meanings of these values.

• The default class parameter is FT_CL_OCTET_STRING.

• The string_length parameter determines the length of each binary

string. HP–UX responders accept an unlimited string_length. If the

string_length parameter is not present, the binary strings are

unbounded.
