I wonder why not use a more abstract level, say simply :
http://www.rddl.org/natures#Schema
which could be used for DTD, W3C XML Schema, Relax NG or other schema

What is found within will tell which one is used.

Moreover, what would happened if I put some Schematron assertions inside 
a W3C XML Schema ?

This is the same with catalogs :
http://www.rddl.org/natures#Catalog
would suit to SGML catalogs, OASIS catalogs, and others

IMHO, it is more close to the idea that a resource belongs to a class or 
group.

I noticed in RDDL some assertions that are very discutable :
http://www.rddl.org/purposes/
Section "Schema related purposes / Validation"
-I could validate a document with a DTD after parsing it, even if the 
document doesn't refer to it (example : because I need to perform 
XInclusion before the validation)
-Schema validation can be also combined with the parse phase.
