++ \brief The OPC UA ContentFilterElement.
++ \since QtOpcUa 5.13
++ \deprecated [6.9]
++
++ A content filter element contains an operator and operands.
++ There are four different operator types which contain literal values, references to
++ attributes of nodes or to other content filter elements.
++
++ A combination of one or more content filter elements makes a content filter which is used
++ by the server to filter data for the criteria defined by the content filter elements.
++ For example, the \c where clause of an event filter is a content filter which is used to decide
++ if a notification is generated for an event.
++
