SAX was originally designed specifically for production use, not for
authoring (to meet the 80/20, or in this case, the 98/2 rule).

That said, comments will be there in SAX2 in the (optional)
LexicalHandler for people who want them, but the lack of comment and
CDATA interfaces have certainly not hindered the SAX application base
so far.

There are only three things that most XML applications need to know

1. Elements
2. Attributes
3. Character Data

It makes a nice little litany: elements-attributes-data,
elements-attributes-data, elements-attributes-data,
elements-attributes-data.  Yes, XML really is/should be that easy.

Actually, apps need to know about error messages too, but that wrecks
