In InDesign CS6 we arrange the order of content using the Articles panel and we expect that the reading order of the exported PDF will match what's in the Articles panel. In reality, we come to find that the layers panel in InDesign adversely affects the reading order. It completely ignores the articles panel which is counter to the purpose. Anyway, I've found that the reading order in the pdf ends up being the reverse order of what is in the InDesign documents layers panel. In terms of Accessibility, this is a problem and requires manual re-organization of the reading order. The Articles panel in InDesign was supposed to alleviate this process. Any ideas?
