There are several possibilities:

- you use an xpointer scheme URI using an XPATH selector

- you use a Text Quote Selector (http://www.w3.org/TR/annotation-model/#text-quote-selector <http://www.w3.org/TR/annotation-model/#text-quote-selector>)

	"target" : {
		source: "URI TO YOUR HTML FILE",
		"selector" : {
			"@type" : "TextQuoteSelector"
			"exact" : "Berlin"
		}
	}

- We are also discussing to have an XPath selector or a CSS Media Query selector; both could also be used.
