Re: Who benefits of PDF tags aside from screen reader users?

Another perceived benefit, though mostly historical, and not
necessarily correct.
- is that PDF documents cannot be alterred accidentally by the user
(any document can be hacked or alterred purposefully, after all all
you need is Adobe Acrobat or similar).

- It is true that forms that require user input can be evaluated much
more easily and user input can be controlled more strictly than with,
say, a Word document or a text document.

Word forms can be created, but they have serious accessibility issues
for screenreader users (though this brings us back to that category).
I am not sure about this, but I believe that users who do not have
Microsoft Word could interact with complex Word forms using, say, a
text editor or Wordpad, though Open Office might do the trick.


A follow up question for the PDF experts in here.
How would you justify creating a PDF form over an HTML one?
