Question: In a 3GPP Contact Manager Provisioning Document, what does the `<Parameter>` element represent when the `<Type>` element is set to `EVENT`?
Option 1: Time interval in seconds before triggering
Option 2: Number of updated contacts triggering the mechanism
Option 3: Version number of the UICC application
Option 4: Type of UICC application triggering the event
Explanation: According to the specifications, when the `<Type>` element is set to `EVENT`, the `<Parameter>` element represents the number of updated contacts. This implies that the triggering mechanism is activated after a specified number of changes to contacts have occurred, highlighting the dynamic nature of contact management in UICC applications.
