My Cocoa document-based app opens and writes custom packages/bundles.
Is this considered a proprietary format that needs to be exported via Exported UTIs (UTExportedTypeDeclarations)?
If so, what should be the values for:
UTTypeConformsTo)public.mime-type)com.apple.nspboard-type)com.apple.ostype)Finally, does the Exported UTI identifier (UTTypeIdentifier) need to be the same value than the Document Type identifier (LSItemContentTypes)?
Trial-and-error findings:

Yes. While I couldn't find any explicit mention of this in the documentation, exporting the type was necessary for Finder to treat the directories as packages.
- Conforms To (
UTTypeConformsTo)
com.apple.package (source)
- Mime Types (
public.mime-type)
Empty. Directories don't have a Mime Type?
- Pboard Types (
com.apple.nspboard-type)
Empty. Pboard Types are deprecated?
- OS Types (
com.apple.ostype)
No clue.

Yes, but I couldn't find any explicit mention of this in the documentation.
