MH-C-EITS
MH-T-PREFERRED-DELIVERY-MODES
Identifies the delivery modes requested by the originator in order of decreasing 
preference. This attribute is included for future use and is relevant only when the form 
of an O/R name is a directory name. (Currently, the GPI does not support the Directory 
name attribute.)
The DDL names for enumerated values of this attribute indicate the delivery modes. 
(See the enumerated values in the Value Characteristics column in Table 3-9
.) In the 
DDL names, PDS indicates physical delivery system (for example, postal system) and 
MTS indicates delivery through the message transfer system. The other names indicate 
types of terminals.
MH-T-PRIORITY
Is the relative priority at which the message was transferred. The DDL names for 
enumerated values of this attribute indicate the priorities. See the enumerated values in 
the Value Characteristics column in Table 3-9
.
MH-T-SUBMISSION-TIME
Indicates the date and time at which the message was submitted.
Implementation and Usage Notes
•
The MH-C-DELIVERY-ENVELOPE class is derived from the set of X.400 
definitions for the P3 protocol. 
•
The GPI does not include the MH-T-MTS-IDENTIFIER in this class. 
•
The MH-T-EXPANSION-HISTORY and MH-T-PREFERRED-DELIVERY-
MODES attributes are 1988 extension attributes. All other extension attributes in the 
MH-C-DELIVERY-ENVELOPE class are mapped to values of the 
MH-T-EXTENSIONS attribute. 
•
Recommendation X.411 recommends that the criticality setting of the 
MH-T-PREFERRED-DELIVERY-MODES attribute be critical-for-delivery.
MH-C-EITS
This class of object summarizes the encoded information types (EITs) represented in the 
content attribute of a message or report. The information indicates whether the object 
can be delivered without conversion.
Table 3-10
 describes the attribute types for this class and the syntax, length, and number 
of values for each type.
