With an explicit <?xml version="1.0" standalone="yes"?>.
Or by telling it to ignore the DTD by doing setLoadExternalDTD(false).

But then, what about parser.setDoNamespaces(false) ?

I'd rather call it unobtrusive (but I'm not 100 % sure this is still
bona fide).
After some testing, I think I'd rather concede that setting the
namespace via the DTD is not necessarily to be universally recommended
as parsers vary considerably as to their default settings, and I admit
I've had problems because I didn't configure the parser appropriately.
