I think, presence of DTD in the XML spec exactly says this (i.e,
validity is a concept inseparably tied to XML markup). But of course,
XML document validity is optional for applications to perform.

Since DTD is already mentioned in the XML spec, why not specify XSD as
well as a normative reference to a future XML spec? I think, even an
errata to a current XML spec can fix this. I am not sure, if another
edition of XML is underway [1]. If that's [1] happening at W3C at the
moment, it may even contain this normative reference I am suggesting.

Even W3C says, that XSD replaces DTD as a better XML validation
technology. And XSD 1.0 version has been in existence since many years
now, and implemented by quite a few XML products, and also deployed
widely in end user applications.
Therefore, why XML standard cannot say that XSD is a validation
technology like what DTD is?

I think, mentioning XSD in the XML spec will encourage users to use
XSD as a better validation technology, than DTD. Mentioning this as a
reference link in XML spec, looks like a very minor and non disruptive
addition to me, for the XML spec.
