Overview

The one-of element is one of the valid expansion elements for the SGR rule element

www.w3.org/TR/speech-grammar/#S2.4 –> XML Form

The one-of element has no attributes

The one-of element identifies a set of alternative elements. Each alternative expansion is contained in a item element. There must be at least one item element contained within a one-of element.

FIXME: Ensure an 'item' element is in the oneof block… this may be at the final draw or when OneOf is called…
