Prior to this commit, the name attribute was unilaterally removed, except for Strict doctypes or a heavy TidyLevel, when it was converted to an id attribute. As name is actually permitted in both HTML 4.01 Strict and XHTML 1.0 Strict, although deprecated, the more sensible default behavior is to allow it unless TidyLevel is heavy. Our implementation is slightly stricter than the specs, as name attributes are treated as first class IDs, disallowing <a name="foo" id="foo"> or duplicate names. The former should be treated as a special case, but that will be a separate commit. Signed-off-by: Edward Z. Yang <edwardzyang@thewritingpot.com>
