`@class` — Authored class styles

	“Look Ma. No stylesheet changes”
	--Test Subject

An early design principle was, “Hands off the @class attribute. That's for user control.” Recently, an approach was implemented that allows authors to define classes and associate specific CSS styles, all within a document.

The @style attribute maps to the oXml -oxy-style CSS property. This allows raw CSS to be passed to the CSS processor for the defined element.

Adding a @styleclass attribute on an element makes the @style value available for reuse. A little XPath handles the indirection from @class, through the preceding @styleclass, to @style:

The first <t/> element defines the style for the class. Others reference the defined styles through the @class attribute
