HTML mixed mode
The HTML mixed mode depends on the XML, JavaScript, and CSS modes.
It takes an optional mode configuration
    option, scriptTypes, which can be used to add custom
    behavior for specific <script type="..."> tags. If
    given, it should hold an array of {matches, mode}
    objects, where matches is a string or regexp that
    matches the script type, and mode is
    either null, for script types that should stay in
    HTML mode, or a mode
    spec corresponding to the mode that should be used for the
    script.
MIME types defined: text/html
    (redefined, only takes effect if you load this parser after the
    XML parser).
