• Updated mensbeam/intl dependency.
• Moved scope methods from Element to OpenElementsStack. They don't need to be used outside of the parser and don't make sense there.
• Cleaned up parse errors. Displaying what is expected or found is not helpful.
• Discovered a way to extend the existing DOM tools, so Parser now works with custom classes for the DOM.
• \dW\HTML5\DOM is no longer needed, and its functionality has been split between DOM\Document and DOM\Element.
• Printer's functionality is now handled by DOM\Document\saveHTML through a trait to make maintenance easier.
• Normalized Exception constants.
• Fixed various typing bugs.
• PHP's DOM returns null when the namespace isn't specified, so it was causing the dispatcher to parse tokens in foreign content when it wasn't supposed to.
• Made the token insertion methods static in Parser so that ActiveFormattingElementsList::reconstruct can insert methods without having to access the Parser instance itself. Might do it differently later, but this works for now.
• Since the fragment context that is passed to Stack can be null it is necessary to check whether the argument is valid before continuing.
• Parser::instance is now protected as all classes are now decoupled.
• Changed the name of the parser instance variable from Parser::$self to Parser::$instance
• Added parse errors for entities into ParseError.
• Moved Parser::fixDOM to DOM::fixIdAttributes.
• Added an exception for when the tokenizer enters an invalid state (infinite looping).
• Made ParseError use Parser::$instance->data instead of a passed around DataStream object.
• Made names of storage property in Stack and ActiveFormattingElementsList consistent to elsewhere
• Parser has its own public static variable that is an intance of itself, so ActiveFormattingElementsList can use that instead of passing an instance around.
• Added separate exception for ActiveFormattingElementsList
• Changes to the spec since the last edit required a rewrite of the tree building algorithm.
• Searching the stack should search from reverse by default because the spec works that way.
• Rewrote StartTagToken because the token attributes need to be easily editable as per the spec foreign attributes are edited before the token goes through the element creation process and not after.
• Yes, there's a goto. Sue me.
