Yep, back in the SOAP days we used to have a lot of XML flying around that would need to be converted into one format or another via XSLT. You can certainly run XSLT on a piece of XML in your own code, but having a dedicated piece of hardware do it for you with a slick GUI was always an easy sell for IBM to management.

Impressed to learn about this hardware for XML processing. I came across an old article that mentioned the price started at $55K!
