	/**
	 * 
	 * Performs property name sorting on a list of properties. Properties
	 * returned are sorted by their (locale-specific) display name. The name for
	 * sorting is assumed to be "groupName.displayName" in which "groupName" is
	 * the localized name of the property group, if any; and "displayName" is
	 * the localized name of the property. That is, properties without groups
	 * sort by their property display names. Properties with groups sort first
	 * by group name within the overall list, then by property name within the
	 * group. Sorting in English ignores case.
	 * <p>
	 * For example, if we have the groups "G" and "R", and the properties
	 * "alpha", "G.beta", "G.sigma", "iota", "R.delta", "R.epsilon" and "theta",
	 * the Properties returned is assumed to be sorted into that order.
	 * 
	 * Sorts a list of <code>PropertyDefn</code> s by there localized name.
