XML was first published as a W3C Recommendation on 10 February 1998.
I would have never dreamt, 15 years ago, that we would be so successful in our dream of exchanging information freely between different platforms and now across devices and clouds. For me, this has been the beginning of the Openness revolution. I truly believe that that the strength of XML is its inherent unique capability of representing homogenously documents and data: those scenarios and capabilities will be even more important for the next 15 years.
Vive XML and to its bright future!
