Actually more then one way. Depends if you want to preserve the entities or
translate them...

All non-standard entities (and there are quit some) should be in the DOCTYPE
declaration at the top of the document.
SO there should be something there like:
<!DOCTYPE doc [
<entity reg ® >]

If you want to preserve the entities you could translate them to some other
string and then put them back in a starttag handler.
You have to construcy the start tag there (modifying the %attrs hash wont
change the attributes in the original element).

Nope ExternEnt is fired when the parser sees an external entity reference
(or was it a declaration)...
