+ - XSS-attempt detection--certain errors are flagged XSS-like
+ - Append something to duplicate IDs so they're still usable (impl. note: the
+ dupe detector would also need to detect the suffix as well)
+
+6.0 release [Beyond HTML]
+ # Legit token based CSS parsing (will require revamping almost every
+ AttrDef class). Probably will use CSSTidy
+ # More control over allowed CSS properties using a modularization
+ # IRI support (this includes IDN)
+ - Standardize token armor for all areas of processing
+
+7.0 release [To XML and Beyond]
+ - Extended HTML capabilities based on namespacing and tag transforms (COMPLEX)
+ - Hooks for adding custom processors to custom namespaced tags and
+ attributes, offer default implementation
+ - Lots of documentation and samples
+
+Ongoing
+ - More refactoring to take advantage of PHP5's facilities
+ - Refactor unit tests into lots of test methods
+ - Plugins for major CMSes (COMPLEX)
+ - phpBB
+ - Also, a FAQ for extension writers with HTML Purifier
+
+AutoFormat
+ - Smileys
+ - Syntax highlighting (with GeSHi) with and possibly tags; may be troublesome
+ because regular CSS has no way of uniquely identifying nodes, so we'd
+ have to generate IDs
+ - Explain how to use HTML Purifier in non-PHP languages / create
+ a simple command line stub (or complicated?)
+ - Fixes for Firefox's inability to handle COL alignment props (Bug 915)
+ - Automatically add non-breaking spaces to empty table cells when
+ empty-cells:show is applied to have compatibility with Internet Explorer
+ - Table of Contents generation (XHTML Compiler might be reusable). May also
+ be out-of-band information.
+ - Full set of color keywords. Also, a way to add onto them without
+ finalizing the configuration object.
+ - Write a var_export and memcached DefinitionCache - Denis
+ - Built-in support for target="_blank" on all external links
+ - Convert RTL/LTR override characters to tags, or vice versa on demand.
+ Also, enable disabling of directionality
+ ? Externalize inline CSS to promote clean HTML, proposed by Sander Tekelenburg
+ ? Remove redundant tags, ex. Underlined. Implementation notes:
+ 1. Analyzing which tags to remove duplicants
+ 2. Ensure attributes are merged into the parent tag
+ 3. Extend the tag exclusion system to specify whether or not the
+ contents should be dropped or not (currently, there's code that could do
+ something like this if it didn't drop the inner text too.)
+ ? Make AutoParagraph also support paragraph-izing double
tags, and not
+ just double newlines. This is kind of tough to do in the current framework,
+ though, and might be reasonably approximated by search replacing double
s
+ with newlines before running it through HTML Purifier.
+
+Maintenance related (slightly boring)
+ # CHMOD install script for PEAR installs
+ ! Factor out command line parser into its own class, and unit test it
+ - Reduce size of internal data-structures (esp. HTMLDefinition)
+ - Allow merging configurations. Thus,
+ a -> b -> default
+ c -> d -> default
+ becomes
+ a -> b -> c -> d -> default
+ Maybe allow more fine-grained tuning of this behavior. Alternatively,
+ encourage people to use short plist depths before building them up.
+ - Time PHPT tests
+
+ChildDef related (very boring)
+ - Abstract ChildDef_BlockQuote to work with all elements that only
+ allow blocks in them, required or optional
+ - Implement lenient child validation
+
+Wontfix
+ - Non-lossy smart alternate character encoding transformations (unless
+ patch provided)
+ - Pretty-printing HTML: users can use Tidy on the output on entire page
+ - Native content compression, whitespace stripping: use gzip if this is
+ really important
