- * What does this do?  The big thing is to handle ol/ul at the top
- * level of list nodes, which should be handled specially by /folding/
- * them into the previous list node.  We generally shouldn't ever
- * see other disallowed elements, because the autoclose behavior
- * in MakeWellFormed handles it.
