Leonard,

    Thank you for your insightful feedback.  I was going a bit nuts
wondering why the form worked in Adobe reader but lacked the keys.  I did
not read the spec as closely as I should have.

    Adding "inheritance support" is probably best left to Dominik and
others who are more familiar with the code base than I.

Dominik,

     How do you want to tackle this issue?  It is fairly easy to remove the
check for HasKey('FT') in PdfPage::GetNumFields() and PdfPage::GetField()...
