Attribute Group Information

Attributes

QName Type Fixed Default Use Inheritable Annotation
CountingFrom DateDurationStartCodeType optional
Role DurationRoleCodeType optional 
This attribute is used to allow qualification orf a
duraiton or durations within a list, in case all durations are provided in the
same location and not below the corresponding funcitonal elements (by default,
flight duration should be in a flight segment but if present below the product
direction, the role can be used). This attribute is usually not used since
position of the duraiton is often enough to understand its intrinsec
role.
Unit DurationUnitCodeType optional 
If not present, the duration is obvious. For
instance, by default a stay is expressed in nights. If several durations are
provided, the unit usually becomes a very important piece of information. It may
still not be required in case the durations are discriminated by other items,
such as their role (trip and stay durations), their values (like 7 and 14 nights
stays)...
