-/**
- * Forgivingly lexes HTML (SGML-style) markup into tokens.
- *
- * A lexer parses a string of SGML-style markup and converts them into
- * corresponding tokens.  It doesn't check for well-formedness, although its
- * internal mechanism may make this automatic (such as the case of
- * HTMLPurifier_Lexer_DOMLex).  There are several implementations to choose
- * from.
- *
- * A lexer is HTML-oriented: it might work with XML, but it's not
- * recommended, as we adhere to a subset of the specification for optimization
- * reasons. This might change in the future. Also, most tokenizers are not
- * expected to handle DTDs or PIs.
- *
- * This class should not be directly instantiated, but you may use create() to
- * retrieve a default copy of the lexer.  Being a supertype, this class
- * does not actually define any implementation, but offers commonly used
- * convenience functions for subclasses.
- *
- * @note The unit tests will instantiate this class for testing purposes, as
- *       many of the utility functions require a class to be instantiated.
- *       This means that, even though this class is not runnable, it will
- *       not be declared abstract.
- *
- * @par
- *
- * @note
- * We use tokens rather than create a DOM representation because DOM would:
- *
- * @par
- *  -# Require more processing and memory to create,
- *  -# Is not streamable, and
- *  -# Has the entire document structure (html and body not needed).
- *
- * @par
- * However, DOM is helpful in that it makes it easy to move around nodes
- * without a lot of lookaheads to see when a tag is closed. This is a
- * limitation of the token system and some workarounds would be nice.
