What is the application level use of XMLPorts (object) in NAV 2016?

"XMLports enable you to import data received in XML format to the Microsoft Dynamics NAV database and export data in XML format from the Microsoft Dynamics NAV database." - This is what I saw in MSDN and Microsoft Partner source site (video tutorials). What I need to know is the practical application of XML Ports.
Does this object have any relation with integration of ISV?

Thank you
