DSL Options

	A wrapper contains "elements" (think of an XML element).
	A wrapper has "slides" (variations on the elements within it).

	An element might exist on every slide of the wrapper (on the 'master slide'),
	or it might exist only on one of the slides.

	An element has attributes.

	* When an element exists only on a particular slide, the attributes also exist
	only on that slide. There is only one value for each attribute.
