DITA to legacy PDF transformation
The legacypdf transformation produces a PDF using the demo PDF build. This transformation is deprecated.
The first versions of the toolkit came with the demo PDF build, which was replaced by the more robust PDF plug-in (also known as PDF2) in release 1.4.3. The demo PDF build is no longer maintained by the DITA-OT developers, although the toolkit includes it in order to support older customizations and build scripts that extended the code.
