Sorry for side-effect, but why do you, people, call SAX API a 'parser' or 
'grammatical layer' ?

In the existanse of yacc and lex -  I think SAX API is a lexer. 
It returns lexems. Tokens. 

For some unknown reasons this lexer has bult-in macroprocessor.

Where is 'grammatical' layer ? Wait ... Attributes? Right ? 

So the only thing which allows us to call SAX API 'parser' 
is it's ability to pack attributes into array ? Right ?

If I'm right on this, this means that to move SAX API closer 
to 'pure lexer' - attributes should fire Attribute 'event'. For example.

On another hand, SAX API could be moved into other direction. 
'more parserish'.

Then schema comes into to the game. 
We'l have a lot of fun down the road. Desiging the real XML *parser*.

Rgds.Paul.

PS. Or I don't understand something and yacc is using wrong 
terminology?  I appreciate a url to the 'correct' terminology.
