Dear XEP-support,
Instead of setting the ENABLE_ACCESSIBILITY option in xep.xml to "true",
I want to set ENABLE_ACCESSIBILITY at runtime with my XSLT-Stylesheet.
How can I do this?
Do you have an example?

Many of our Us Gov customers actually generate both. That way, they can still meet requirement of 508 but not overly burden users that don't need the enhancements that 508 documents deliver.

Makes good sense Kevin, thanks.

Paul:
Enabling Tagged PDF through Accessibility has the effect of embedding essentially the XPATH to every element in the PDF on every object. This is the "tagged" part.
If you were to examine the XEP Intermediate Format, you can get an idea of this:
Without ...
<xep:text value="Rewards:" x="108584" y="514977" width="51618"/>
With ...
<xep:text value="Rewards:" x="108584" y="514977" width="51618" xpath="/*[1][name()='root']/*[3][name()='page-sequence']/*[2][name()='flow']/*[2][name()='block-container']/*[1][name()='block']/*[1][name()='inline']"/>
The xpath information must be embedded into the PDF to understand structure from the source as this is the requirement of 508. Thus, it significantly increases the size of the PDF as the xpath itself is much larger that the content (in this case, just the word "Rewards:". This is especially true when it comes to tabular structures -- you may have root->page-sequence->flow->block-container->block->table->table-body->table-row->table-cell->block->inline ... for each and every cell (and if you nest tables ..... think of it).

Hi,
I am trying to create a "508-compliant" PDF file using RenderX (4.17) by setting the ENABLE_ACCESSIBILITY option in xep.xml to "true". For the document in question this increases the file size from 167K to 1009K. If COMPRESS is set to "false", the file size increases further, to 1563K.
I'd like to know if there's a way to avoid the large file size.
Thanks,
Paul
