I'd really appreciate if the documentation spelled out exactly how

To give an example of a specific NSDocument usage that I'd like to
know about: how does asynchronous saving use
The header documentation for -performSynchronousFileAccessUsingBlock: (which
also applies to performAsynchronousFileAccessUsingBlock:) says:

NSDocument's NSFilePresenter methods use

I'm working on a document-based application, and am a bit befuddled by
-performSynchronousFileAccessUsingBlock:. The documentation says that
NSDocument itself consistently uses this mechanism around invocations
of the following methods: and lists methods including -fileType,
-fileURL, etc. The
