This certainly works and I "discovered" this solution myself. Can't say if
it's the simplest or most elegant, though.

If you have the children can push themselves to the parent during
invokeBody(...), then the parent can process them after the call to
invokeBody(...), no?
// parent code:
public void doTag(XMLOutput output) throws Exception {
invokeBody(output); // children push themselves up...
processChildren(); // iterate over children doing whatever
}
