group
|
(optional) Add the contexts to one of five numbered context groups, numbered 0–4.
When PTC ALD checks the available list of contexts, it will return the single most specific context from each different group specified, using normal priority rules.
The set of contexts assigned to the stream (if present) is considered group 0. If adding to this group results in multiple contexts being found, each result will be processed in the group number order, with any results from group 4 first, and group 0 last. This allows up to 5 different matches to be processed at the same time.
If a group number is not specified in the command, the additional contexts specified in that instruction will be added to group 0.
The most applicable context from each group is applied:
• onEnter tags are applied in the order of group 4 to group 0.
• onExit tags are applied in the order of group 0 to group 4.
