XML Worker is no longer in beta!
This 1.0.0 fixes plenty of table and list problems that were reported on http://demo.itextsupport.com/xmlworker/
The internal architecture was changed: we removed "tag listeners" in favor of "pipelines" that are chained together: parsing HTML, parsing CSS, creating PDF.
We've added LinkProvider and ImageProvider functionality (similar to what we had in the old iText HTMLWorker).
Finally, we've also fixed numerous bugs.
