The document says in the introduction, [[
More specifically, this specification defines an XML signature element
type and an XML signature application; conformance requirements for
each are specified by way of schema definitions and prose respectively.
]]

So the schema is part of the specification.

Maybe you are asking whether software that validates signatures must
read and use that XML Schema? No, but it must conform to it.
