- Fixed buggy chameleon-support for ins and del . Removed context variable ParentType, replaced with IsInline, which is false when you're not inline and an integer of the parent that caused you to become inline when you are (so possibly zero) . Removed ElementDef->type in favor of ElementDef->descendants_are_inline and HTMLDefinition->content_sets . StrictBlockquote now reports what elements its supposed to allow, rather than what it does allow . Removed HTMLDefinition->info_flow_elements in favor of HTMLDefinition->content_sets['Flow'] . Removed redundant "exclusionary" definitions from DTD roster . StrictBlockquote now requires a construction parameter as if it were an Required ChildDef, this is the "real" set of allowed elements git-svn-id: http://htmlpurifier.org/svnroot/htmlpurifier/trunk@710 48356398-32a2-884e-a903-53898d9a118a
