I made the change in order to make it easier to process the data with a top-down, recursive descent parser approach.

I.e.
	peek at next start_tag
	call handler for the right start_tag

That way, start_tag handlers could handle all the attribute processing, rather than the main
parsing loop having to stack up attributes for some yet-to-be determined element type.
