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.

Could you elaborate? I am really curious how this hardware worked.

Was it a HTML Gui with file upload and everything? Or just some server, port and proprietary protocol?

Maybe these things are on Ebay for cheap. Oh, that looks like fun.

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