The Lint Filter ensures that all data (tag and attribute names, attribute values, comment data, text and doctype names) are unicode() strings.
_base.TreeWalker ensures only unicode() strings are emitted. This is probably not the best way but it works and is better than having tokens with non-unicode strings live on token streams. --HG-- extra : convert_revision : svn%3Aacbfec75-9323-0410-a652-858a13e371e0/trunk%40687
