In my plugin, I use Apache Tiles, which require a reference to a DTD in their layouts/views XML declaration files. I am trying to create these files from a template, and then add more view/layout definitions later in the plugin's workflow.

However, depending on how the DTD reference (in the format <!....>) is added, it is either omitted from the generated file or causes an exception when the XML Parser tries to parse the file for the root node.
