-/**
- * Injects tokens into the document while parsing for well-formedness.
- * This enables "formatter-like" functionality such as auto-paragraphing,
- * smiley-ification and linkification to take place.
- *
- * A note on how handlers create changes; this is done by assigning a new
- * value to the $token reference. These values can take a variety of forms and
- * are best described HTMLPurifier_Strategy_MakeWellFormed->processToken()
- * documentation.
- *
- * @todo Allow injectors to request a re-run on their output. This
- *       would help if an operation is recursive.
