PDF Tag Nesting Question

for

Hi!

Our office is lucky enough to have two staff members working on making PDF documents accessible - most notably to adhere to 508 accessibility laws. The staff members have different backgrounds and training in accessibility and have a question about the proper/best way to tag a PDF - one staffer nests the tags and another does not. Is one more correct/more accessible than the other?

Non-nested example:
<H1>
<P>
<H2>
<P>
<P>
<L>
<H3>
<P>
<H2>
<P>

Nested example:
<H1>
<P>
<H2>
<P>
<P>
<L>
<H3>
<P>
<H2>
<P>

So, does the nesting or non-nesting make a difference in accessibility? Our team has limited resources to screen readers for testing and want to ensure we adhere to true accessibility and not just merely what an automated checker can validate.

In addition, the two staffers have differing approaches to using the <Sect> tags. One uses them, the other does not. Please advise as there are differing guidelines provided depending on the source.

Is there a definitive resource on how all of the tags should be used so these are less open to subjective interpretation?

Thanks in advance!
