Auto-generated references blocks
If the source wikitext had &lt;ref> tags but no corresponding &lt;references> tag to generate references, Parsoid auto-generates references blocks for every set of refs that need it. As of HTML version 1.2.1 (as of Friday, March 25, 2016, the production version of Parsoid on the WMF cluster is still at version 1.2.0), for all such auto-generated reference block, the data-mw will have the autoGenerated property set to true.
