Well, I came up with a way to do it. I wrote a new class called
TextTemplateResourceReference, which you can use along with a
StyleSheetReference. Basically, you just pass it in a model for the
variables to plugin. I don't know about that lastModifiedTime()
implementation, but its overridable if anyone wants to do something
different. If anyone wants the code to turn a java.awt.Color object into a
hex string appropriate for CSS stylesheets, let me know. I've got that
floating around somewhere.
