Using Wildcards
To register or cancel a subscription for multiple event types, you may use a single wildcard character "*" at the end of the event type name.
If you use wildcards in the event type name, the following restrictions apply:
Only those event types that your client has permission to subscribe to will be included in the subscription.
Wildcards cannot be used with any event type within the scope of
Broker::Trace or
Broker::Activity.
If a filter string is specified for the subscription, it may not contain any data fields. The filter string may contain envelop fields, however.
