universal	-	*	{ type: 'universal' }
pseudo	name, data	:name(data)	{ type: 'pseudo', name: 'name', data: 'data' }
pseudo	name, data	:name	{ type: 'pseudo', name: 'name', data: null }
pseudo-element	name	::name	{ type: 'pseudo-element', name: 'name' }
attribute	name, action, value, ignoreCase	[attr]	{ type: 'attribute', name: 'attr', action: 'exists', value: '', ignoreCase: false }
attribute	name, action, value, ignoreCase	[attr=val]	{ type: 'attribute', name: 'attr', action: 'equals', value: 'val', ignoreCase: false }
attribute	name, action, value, ignoreCase	[attr^=val]	{ type: 'attribute', name: 'attr', action: 'start', value: 'val', ignoreCase: false }
attribute	name, action, value, ignoreCase	[attr$=val]	{ type: 'attribute', name: 'attr', action: 'end', value: 'val', ignoreCase: false }
