@lettosprey about 2010 I worked for a supply chain company that had issues integrating data provided by multiple upstream suppliers
A consultant: "But they are switching to XML, so if they all give you XML and your system imports XML it will all just work"
Me: "...it doesn't work like that"
Them: "eh?"

Me: "XML isn't a data format, it's a way of creating data formats. A web page is XML. Our accounts package can import XML. If I try importing our company home page into our account package...it's not going to be able to do anything useful"
Them: "...ohhhhh. Nobody has ever actually explained it to me like that before."
