How to add jsf components to taglib programmatically

I was wondering if it's possible to add JSF components to the tag library programmatically? I'm implementing a plug-in mechanism in our application. And now, if I create a JSF component in the plug-in, I need to change the components taglib xml file in the main application, which is not the goal. I'd rather like to put a components taglib xml file inside a plug-in which is then handled by the main application. Is there any way to do that?

The reason why I'm asking this is the following: In our application, we send secure messages through a web interface. The messages are created by filling out forms, which are, in most cases, generated. But some forms have special开发者_StackOverflow behavior and we don't want to release the whole application if a new 'special form' is implemented, so we decided to put these in plug-ins.

Thanks for any help.

Cheers, Andreas
