Re: Use of Headings

I completely agree!

One of the problems with using tables for layout is that they are often not
retained as inserted. For example a document author might start off with a 6
column table and then adjust the number of columns to fit the content...not
data table content...and what ends up happening is that part of the table
used for layout is converted to a data table inappropriately while other
pieces of the table aren't.

What this means for someone using a screen reader is that content that
doesn't seem to fit a table structure is plunked into one. This affects
comprehension and readability and is very confusing.

The fact that table-tools were used to author the document should not be
taken to imply that tables should be represented in the document's tags.
Semantics should always trump the machine output.

Then tag it that way, replacing the "detritus" table tags left over from the
PDF's creation.

Yes... so the tags in the PDF as-created are incorrect and must be edited in

Modify the logical structure in the PDF to match the semantics of the
