Reference to text attribute value

I need a reference to a text item in a other collection, see below

'labels': collection ['label'] {
  'label': text
  'label2': text
}
'names': collection ['name'] {
  'name': text
  'name2': text -> ^ .'labels'.'label2'
}

The last line gives an error, how can I get a reference to label2?

In Alan, text references point to collection entries. To unambiguously reference a collection entry, the value of a text reference should always be a key value: label in your code sample. To show additional values like label2 in the GUI, you can do this:

'labels': collection ['label'] {
	'label': text
	// use @identifying to always show the label2 value 
	// at label references in the GUI
	'label2': text @identifying 
}
'names': collection ['name'] {
	'name': text
	// use @show: to show the value of label2 in addition to 
	// the keys of labels (obsolete when using @identifying)
	'name2': text -> ^ .'labels'[] @show: ( 
		'label2': text
	)
}
