I bet that adding XML will make your car shinier too. This story from Frank Hayes mentions in passing that XML came up in senate testimony of a new FBI information system:

Yes, it's nice that Sentinel will also be fully buzzword-compliant: Mueller told the senators the system will use XML to facilitate information sharing, which must have impressed the politicos greatly. But the actual technology is background noise.

I'm just pondering the notion of XML coming up in testimony to a senate panel. It's like waving a gollum doll to drive away demons, I guess...
