Detailed Description

Provides the linking to subelements within a OpcUa_ContentFilter.

The link is in the form of an integer that is used to index into the array of elements contained in the OpcUa_ContentFilter. An index is considered valid if its value is greater than the element index it is part of and it does not reference a non-existent element. Clients shall construct filters in this way to avoid circular and invalid references. Servers should protect against invalid indexes by verifying the index prior to using it.
