On the negative side, we had to endure managers coming back from “XML conferences” and recommending we ditch our
Oracle or Sybase or whatever and replace it with an XML database, because XML.
On the plus side, vendors made sure to support it so to this day we have good tooling in Eclipse, VS, etc.
Also on the bad side they have gone crazy overboard so we have security issues like this:

So I still have WS endpoint but I rewrote it to manually parse XML and avoid all the crappy extensions that they put in and I cannot disable.
So yeah, this is loaded… I am not promoting XML. It has its issues. Use what you like.
