Not used by any call.
The suggested order in which the characteristic should be presented to the user in a list. Indicates the relative position of the sort key in the list of characteristics. The characteristic with the lowest display sequence is considered the default sort key in calls to GetProductSearchResults. Aside from that, usage of this display sequence information is optional. For example, in an application with a graphical user interface, a characteristic with a display sequence of 2 could be presented before one with a display sequence of 3 in a drop-down list. If multiple sort characteristics are returned for a characteristic set, compare their display sequence values to determine the lowest available value (usually 0) and the overall sequence.
