<!DOCTYPE R> is a doctype decl, yet the DocTypeHandler doesn't get called
(although the parser did parse it). I am writing an application which
attempts to preserve most of the sturcture of the original XML file, so in
response to the event I would simply note that there is a doctype decl with
R for the root and no system or public id.
You must have a DOCTYPE decl to have an internal/external subset but you
don't need an internal/external subset to have a DOCTYPE decl. Having a
DOCTYPE decl and having subsets are two different things.
If there is no internal or external subset, why should the auto mode
attempt to validate the document? It must fail because there is no
declaration for the root element. If the current behavior is the correct
behavior, at least the documentation should change. The documented
behavior makes more sense to me.
BTW I get different errors when parsing "<!DOCTYPE R><R/>" with Val_Always
vs Val_Auto.
In answer to your question about why would you have a doctype decl without
subsets, I don't know why you would do that. I was just arguing that the
doctype handler should be called because it is legal XML syntax.
