The newest autoclose code uses the elements property in whether or not an element should be closed by a particular tag. The heuristic is simple; if the element doesn't allow that tag as a child, it closes the parent container. This doesn't work, however, with <blockquote>, which while not allowing inline styles under Strict doctypes, requires them to be passed through MakeWellFormed. The fix was to transition MakeWellFormed to call a method to retrieve the elements, and then have StrictBlockquote implement a special version of this method. Future versions of HTML Purifier may be more flexible in this regard--further study of the HTML5 specification is required. Signed-off-by: Edward Z. Yang <edwardzyang@thewritingpot.com>

All about HTML Purifier
HTML Purifier is an HTML filtering solution that uses a unique combination
of robust whitelists and agressive parsing to ensure that not only are
XSS attacks thwarted, but the resulting HTML is standards compliant.
HTML Purifier is oriented towards richly formatted documents from
untrusted sources that require CSS and a full tag-set. This library can
be configured to accept a more restrictive set of tags, but it won't be
as efficient as more bare-bones parsers. It will, however, do the job
right, which may be more important.
