I currently work with xml that is up to15 years old and sgml (still!) that can be 20-25. Some of the contents are laws or cases over 350 years.
My company's expectation certainly is that the information will last hundreds more years, in some evolving number of formats. Globalization, new delivery platforms, and the end-of-life for operating systems are the main drivers for schema replacement.
Cheers
Rick
