Michael Klink commented on PDFBOX-1802:
---------------------------------------
I don't think it is a matter of whether or not the OP has a sample document but
of whether or not the specification allows it.
The PDF specification [ISO
32000-1|http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf]
in section 7.3.6 *Syntax --> Objects --> Array Objects* states that
{quote}
an array’s elements may be any combination of numbers, strings, *dictionaries*,
or any other objects, including other arrays,
{quote}
and in section 7.3.10 *Syntax --> Objects --> Indirect Objects*
{quote}
Except were documented to the contrary any object value may be a direct or an
indirect reference.
{quote}
The only obvious exception are stream objects because
{quote}
All streams shall be indirect objects
{quote}
according to section 7.3.8.1 *Syntax --> Objects --> Stream Objects -->
General*.
Thus, even if there may be no need to have direct dictionaries in PDFs to form
the explicitly defined structures in the specification (I have not checked in
detail, maybe there *is*), such objects may be used in extensions of the
standard and, therefore, necessary.
