In the website terms and conditions document, the notes to section 3.1(e) refer to "dynamic services". Please could you clarify what this covers?

Alasdair Taylor's answer to Question about website T&Cs (1206916436)

Answer to the question: 

This refers for example to any data processing or software-based services offered through a website. For example, messaging services, mapping services or data storage services might be covered by this. Depending upon the services that you are offering through your website, you may need to consider whether any special licensing rights or restrictions should be added to the document.
