Jumping in late, but that's not gonna work. One possibility is to create a
"dispatch" tag that you use like:
<tag_prefix:dispatch target="${i}"/>
And if you still want to be able to use <tag_prefix:xyz/>, etc. "statically",
you'll probably want to create a delegate class that contains the real
functionality and can be used by both the dispatch and "static" tags.
BTW, is this just curiosity on your part or do you have a real use case where
this seems appropriate (like generating tag tests maybe)? If you really have a
use case, perhaps sharing that would help generate more effective feedback.
