to help them get the "cleanest" PDF files possible. I would

<p><font size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>get
some feedback from those of you who regularly use the Adobe Acrobat 7.0</span></font><o:p></o:p></p>
<p><font size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>accessibility
checkers and do lots of tagging and alterations of document</span></font><o:p></o:p></p>

<p><font size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>I
have some questions regarding files that originate in Microsoft Office or</span></font><o:p></o:p></p>

<p><font size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>1.
Sometimes, after running the accessibility check, I get an error message</span></font><o:p></o:p></p>
<p><font size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>that
"Acrobat was unable to make this document accessible because it could</span></font><o:p></o:p></p>

After running an accessibility check, sometimes I get a message that</span></font><o:p></o:p></p>

are x number of words with characters that do not map to Unicode."</span></font><o:p></o:p></p>

or suggestions on this?</span></font><o:p></o:p></p>
<p><font size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>3.
I've also gotten error messages that say, "x number of elements were not</span></font><o:p></o:p></p>

I've also run OCR on a PDF that looked like it was an image only PDF</span></font><o:p></o:p></p>
<p><font size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>with
some math notation. When I have run an accessibility check on the</span></font><o:p></o:p></p>

<p><font size=2 face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>hardly
