Låt oss då prova ett praktiskt experiment. Vi har en (outtalad)
överenskommelse om att använda engelska i den här mailinglistan. Nu
ändrar jag den, vilket ger samma konsekvenser som om jag ändrade
markupen i ett XML-dokument.

Visst kan du läsa det här, men medge att det kräver mer arbete än om jag
hade hållit mig till det språk vi kommit överens om att använda.

Applikationer som är tillräckligt smarta för att förstå markup utan att
vara hårdkodade för den kommer i slutändan att behöva vara ungefär lika
komplexa som en applikation som förstår mänskligt språk. Den dagen
behövs inte XML längre. Vi kommer nog dit så småningom, men än är det
långt kvar.


PS. Just an example of exchanging information without contracts and
agreements, and without prenegotiating a format.
