3.8 Finding And Exploring Entries
There is a mechanism that allows users to check whether the entry with the given name exists and to obtain a kind of ``proxy'' object, or ``pointer'' that allows to reference the found entry without addressing it by name again.
This ability is important for those programs that dynamically interpret the message content or where it makes sense for the data to have optional entries.
