Knowing Mikhail (author of wikimodel) I'm pretty sure he has added  
these events for a good reason. I'll try to ask him why he had a need  
for the other events.

Let's take the onSpecialSymbol() for example. Imagine the following  
use case: escaping all XML/HTML in the page. The way wikimodel does  
this is by sending events when the "<" and ">" chars are encountered.

How would we do this in Doxia? If we add the onWord event, then will  
it include special characters too? Let's say it does and we get  
"words" like "<img .../>". If we wanted to escape XML/HTML we would  
need to reparse each word and check for "<" and ">" chars. Is that the  
best way of doing it?

OTOH sending events for each special char is probably performance- 
consuming so you may not want to emit these events in all cases.

Maybe one solution would be to have different parsers for different  
needs. And to have 2 Sink interfaces. One for coarse-grained events  
and one for fine-grained ones.

WDYT?

Thanks
