I don't think you've looked very hard. The WDs for XHTML 2.0 and for MathML3
are two examples I quickly found of W3C specs that provide RelaxNG schemas.
In MathML we find the statements:

* MathML documents should be validated using the RelaxNG Schema for MathML

* MathML fragments can be validated using the XML Schema for MathML

(see http://www.w3.org/TR/2009/WD-MathML3-20090924/appendixa.html)

I'm sure there are many other examples. These conspiracy theories about W3C
are quite unfounded. W3C does try, on the whole, to keep its specs
architecturally aligned with each other, so there is obviously going to be
some encouragement to working groups to follow the party line (that's why
XQuery ended up being a superset of XPath rather than a completely different
language), but in the end, the technical decisions are made by individual
WGs - which means, in effect, by individuals like you and me, sometimes
influenced to a greater or lesser degree by the companies they work for.
