Working with a PDF package

Question

I've got a (fairly) simple PDF file that is a PDF package.
I can't seem to find any information how to 'get' at the PDFs within the package (for printing).
I have this code to print a simple PDF:
    Dim PDF2 As Acrobat.CAcroPDDoc
    Dim av As Acrobat.CAcroAVDoc
    Set PDF2 = CreateObject("AcroExch.PDDoc")
    'Open main PDF document
    'Plain PDF document:
    PDF2.Open "G:\plain.pdf"
    'PDF document as a package
    'PDF2.Open "G:\packaged.pdf'"
    'Print just the first page of the file to the default printer
    Set av = PDF2.OpenAVDoc("Title")
    av.PrintPagesSilentEx(1, 1, 0, 0, 1, 0, 0, 0, 0)
    av.Close True
For the file 'packaged.pdf', how do I print the first page of the first PDF inside it? Or all the pages of all the PDFs?
The IAC developer guide at http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/iac_developer_guide.pdf?bcsi _scan_A4C9E8056B19D97F=0&bcsi_scan_filename=iac_developer_guide.pdf
doesn't even mention packages.
Neither does the IAC API reference at http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/iac_api_reference.pdf?bcsi_s can_A4C9E8056B19D97F=0&bcsi_scan_filename=iac_api_reference.pdf
What am I missing?
Thanks for any help.

You may have to use the JSObject interface, which will allow you to open the attached files, which are data objects. See the Acrobat JavaScript documentation, starting with the "dataObjects" document property and go from there. For printing, see the "print" document method.
