-------------------------------------------------------------------
Proposed patch. My thought:
- Both PDField and PDNonTerminalField are of the type PDFieldTreeNode
- The hierarchy property thing isn't really relevant here, because we just need
to know if any field has something "forbidden"
Weird stuff: checking the file 006654.pdf with pdf-tools brings "The document
contains actions types other than for navigation (Launch, JavaScript,
ResetForm, etc.)." among many other errors. Where are these action types? My
understanding is that these are /A and /AA and they're not at any field in this
file.
