XML is not a replacement for SGML. XML is a form of SGML.

And I do not see the benefits of an existing library as
an indication of a problem. It is natural to reuse code.

I do agree that XML has become rather complex. There are
some "design by committee" signs in it. DTD is much simpler
than schemas. Sure schemas can provide more information, but
is it really needed.

One has to evaluate whether the benefits outweigh the cost of
the extra complexity.

I think JAXB and StAX was worth it.

Given that XML parser has required no extra jar files since
Java 1.4 released in 2002, then that argument has not much
validity today.

Even SAX, and occasionally one of the DOMs.

JAXB is especially painless.
