Yes, but the headless XML also has those constraints, so they need not
be at issue. The issue is that a document does not forceably constrain which
class of parser is required to get its infoset: I think standalone has failed
because it requires a too unrealistic smigeon of work at both ends to make it
reliable.*
Given that we have other schema languages floating around now, if a
DOCTYPE is specificied, the expectation of a parser should be that it
means the document is not standalone: that the DOCTYPE exists because
it provides entities and defaults an ID information rather than for QA.

* Anyway, in SAX 2, we can get the http://xml.org/sax/features/is-standalone/ value only after we have started parsing, but we cannot change the value of http://xml.org/sax/features/validation while parsing. The ship has already set sail.
