Summary:
Consider the following XML:

<?xml version="1.0" standalone="yes" ?>
<!-- comment1 -->
<!DOCTYPE xxx SYSTEM "XXX" [
	<!-- comment2 -->
	<!ENTITY blah SYSTEM "BLAH" NDATA note>
	<!NOTATION note PUBLIC "my notation">
	<!ELEMENT xxx (#PCDATA)>
]>
<xxx>some text</xxx>

NSXMLParser does not have a means of indicating it has entered the DOCTYPE stanza, which means that I can't tell whether comment2 is part of the DOCTYPE or part of the XML body.

My app parses and reformats XML documents, so this information is crucial.

I thought that I could perhaps use NSXMLDocument instead (even though I lose all the benefits of the streaming parser), however, it has a different problem which means I can't get back the notations (see bug report 18975903) so that isn't a meaningful workaround.

Steps to Reproduce:
Run the attached project and view the console output.

Expected Results:
There should be some indicator that the DOCTYPE has been entered.

Actual Results:
The foundComment method is called, but with no context to indicate we are inside (or outside) the DOCTYPE
