Isn't there value in the ISO imprimatur for ISO/IEC 19757-2 RELAX-NG and 
ISO/IEC 19757-3 Schematron?

Do vendors feel these standards are not worthy?

I ask because I have the impression that users follow the lead of tool 
vendors more often than learning the technologies well enough to roll their 
own ... so the "acceptance" of a technology is often related to how many 
vendors support it.

So what is holding vendors back from ISO-developed standards?

I won't accept "overlap" as an answer because W3C Schema describes 
type-based constraints, RELAX-NG describes pattern-based constraints, and 
Schematron describes assertion-based constraints.

Horses for courses.
