- Buggy treatment of end tags of elements that have required attributes fixed (does not manifest on default tag-set) - Spurious internal content reorganization error suppressed . Error unit tests can now specify the expectation of no errors. Future iterations of the harness will be extremely strict about what errors are allowed git-svn-id: http://htmlpurifier.org/svnroot/htmlpurifier/trunk@1424 48356398-32a2-884e-a903-53898d9a118a
