Document.enableAddingSpecialTagsToDom

This will set delegates for parseSaw* (note: this overwrites anything else you set, and you setting subsequently will overwrite this) that add those things to the dom tree when it sees them. Call this before calling parse(). Adds objects to the dom representing things normally stripped out during the default parse, like comments, <!instructions>, <% code%>, and <? code?> all at once.

Note this will also preserve the prolog and doctype from the original file, if there was one.
