It's currently really just an internal method of doing chaining of converters.
You could write a support component, that reaches up into the parent UIInput, grabs the converter, checks if it is a ConverterChain, and then runs the addConverter method if it is.
File a feature request in JIRA if you like for a better way to use the converter chain (its the first request I've seen).
Thanks a lot for this quick answer Pete!

Just for verification of my understanding:
That means implementing a ui component similar to <s:convertEntity> ?
What I'd give for a convertEntity that works with Hibernate (non-EJB) :/
