+ * The parser parses tokenized input into the document, building up the
+ * document tree. If the document is wellformed, parsing it is
+ * straightforward.
+ * Unfortunately, people can't write wellformed HTML documents, so the parser
+ * has to be tolerant about errors.
+ *
+ * We have to take care of the following error conditions:
+ * 1. The element being added is explicitly forbidden inside some outer tag.
+ *    In this case we should close all tags up to the one, which forbids
+ *    the element, and add it afterwards.
+ * 2. We are not allowed to add the element directly. It could be, that
+ *    the person writing the document forgot some tag inbetween (or that the
+ *    tag inbetween is optional...) This could be the case with the following
+ *    tags: HTML HEAD BODY TBODY TR TD LI (did I forget any?)
+ * 3. We wan't to add a block element inside to an inline element. Close all
+ *    inline elements up to the next higher block element.
+ * 4. If this doesn't help close elements, until we are allowed to add the
+ *    element or ignore the tag.
