-/**
- * Proof-of-concept lexer that uses the PEAR package XML_HTMLSax3 to parse HTML.
- *
- * PEAR, not suprisingly, also has a SAX parser for HTML. I don't know
- * very much about implementation, but it's fairly well written. However, that
- * abstraction comes at a price: performance. You need to have it installed,
- * and if the API changes, it might break our adapter. Not sure whether or not
- * it's UTF-8 aware, but it has some entity parsing trouble (in all areas,
- * text and attributes).
- *
- * Quite personally, I don't recommend using the PEAR class, and the defaults
- * don't use it. The unit tests do perform the tests on the SAX parser too, but
- * whatever it does for poorly formed HTML is up to it.
- *
- * @todo Generalize so that XML_HTMLSax is also supported.
- *
- * @warning Entity-resolution inside attributes is broken.
