> See PDF Reference, Third Edition, Section 3.8.5, "Number Trees": the Nums entry
> must be an array of key-value pairs where value is an indirect reference to the
> object associated with the key.
> However, the o.a.f.pdf.PDFNumsArray class does nothing to ensure that elements
> added to the array are actually indirectly referenced. So generated PDFs are
> strictly speaking invalid.
