Re: Shapes/ShEx or the worrying issue of yet another syntax and lack of validated vision.

Why take out all of them instead of removing the one that's immature? Near
as I can tell ShEx is less than a year old. Does W3 Team really think it
should be promoted in place of something like SPIN or ICV, which are 5 or 6
years old? That's indefensible.

Cheers,
Kendall
