When exporting ODF to PDF (in Writer or another LibreOffice component), the author can/should check several options in the export dialog to produce tagged and accessible PDF:
* the options "Tagged PDF" and "Export bookmarks" on the General tab,
* the option "Bookmarks and page" on the Initial View tab (because many users who can benefit from bookmarks don't know they exist).
It is a good thing (!) that these options remain checked after the first time, but it would be even better if they were already checked by default (i.e. right after installation): many documents are sufficiently accessible to benefit from tagged PDF export, but most authors don't know that tagged PDF exists or what it means.
Enabling tagged PDF by default won't turn inaccessible ODF files into accessible PDF, but it would make many PDF files much easier to navigate with a screen reader. In untagged PDF, screen reader shortcuts for navigating documents (h for heading, t for table, p for paragraph, etc) won't work.
http://blogs.adobe.com/acrolaw/2006/01/understanding_t_1/ explains what tagged PDF is and why it matters.
It's an Accessibility issue but i couldn't find how to flag that up.
Microsoft Office 2010's built-in PDF export produces tagged PDF. I have not found a way to turn this off.

This bug was filed before the changes to Bugzilla on 2011-10-16. Thus it
started right out as NEW without ever being explicitly confirmed. The bug is
changed to state NEEDINFO for this reason. To move this bug from NEEDINFO back
to NEW please check if the bug still persists with the 3.5.0 beta1 or beta2 prereleases.
Details on how to test the 3.5.0 beta1 can be found at:
more detail on this bulk operation: http://nabble.documentfoundation.org/RFC-Operation-Spamzilla-tp3607474p3607474.html
I confirm that this functionality request is still relevant to LibreOffice 3.5.0 RC1 (i.e. bookmarks are exported by default, but tags are not) and change the status from UNCONFIRMED to NEW.

Tagged PDF option still not checked by default under v188.8.131.52 when exporting to PDF.
Removing comma from Whiteboard (please use a space to delimit values in this field)
Migrating Whiteboard tags to Keywords: (a11y -> accessibility)
So "export bookmarks" is already enabled, so 1 of 3 is already done. Enabling "bookmarks and page" seems fine as we have already enabled "export bookmarks" and pdfs with no bookmarks arent affected by this setting. "tagged pdf" is the main issue to discuss as the help states "Selects to write PDF tags. This can increase file size by huge amounts.", so i'm not to sure about enabling this by default.
@Heiko, @Stuart, @Cor, @Adolfo: What are your takes?

Do some tests on file size..
But I agree with Christophe about the benefit. Think I would give that more weight..
While this is simply a toggle control in the export dialog, so should be simple to implement. Think it is correct to do as a default setting to produce tagged PDF by default.
More important but much more work would be to refactor the tagged PDF to produce PDF/UA compliant PDF (bug 45636).
So i tested a few docs i had from my compatibility testing days and here is the change in size.
747.4 KiB -> 3.9 MiB (+433%) 
979.5 KiB -> 1.5 MiB (+52%) 
515.0 KiB -> 680.3 KiB (+325) 
160.6 KiB -> 198.6 KiB  (+24)
184.8 KiB -> 385.7 KiB  (+109%)
405.7 KiB -> 484.6 KiB (+19%)  (a google doc i threw into the mix)
So in half of the cases, the size more than doubles and the other half it less than doubles, so it all comes down to how much structure the file has and whether users will complain about their pdfs growing way to much.

How about checking "Archive PDF" by default? This option includes the tagged feature and produces more standardized results. Otherwise I think average documents are small enough to deal with double its size. We do not talk about 100MB files.
"Create PDF Form' is enabled by default and enabling "Archive PDF" disables that option. Also when i tested exporting a file (number 6 from comment 12), it gave some warnings of loss of features and the file size jumped 50% compared to the tagged pdf version, so i wouldnt think it would be suitable as default for the masses.

I'm also in favor of enabling archive PDF by default because it's less problematic to increase size of PDF than creating inaccessible PDFs.
Also, Microsoft Office exports to accessible PDF by default.
@Heiko: Do you know who is aware on how to change a default settings in LibreOffice? I assume it's trivial for someone aware of this.
