Extension point for providing custom content assis

Question

I am writing eclipse plugin to add better support for properties files. One of the missing piece is content-assist ... I'd like to show matching properties keys when user starts typing some string and presses content assist key.

For example, when I have property hello = world in one of my properties files, and I start typing format("hel and hit CTRL+SPACE now, I'd like to see available hello property.

My problem is that I cannot find correct extension point to provide custom content assist processor. How can I provide my own content assist processor for text files? I'd like to make it work mainly in Java, JSP and XML files.

This is not extension based solution, but may still benefit you.
