On 10 February 1998, W3C published Extensible Markup Language (XML) 1.0 as a W3C Recommendation. W3C would like to thank the dedicated communities — including people who have participated in W3C’s XML groups and mailing lists, the SGML community, and xml-dev — whose efforts have created a successful family of technologies based on the solid XML 1.0 foundation.
XML is 10! Impressive when you think that I was in a web agency in 1999 and it was already part of the technical surroundings. It spread really fast. Happy anniversary XML!
