is it possible to travel upward in data binding? like $.parent.parent.data?

hi there,

I'd like to ask a question that is it possible to travel upward in data binding? like $.parent.data?

we have xml like below

<level1>     <name>Name</name>     <level2>          <data>Data</data>     </level2></level1>

and in XDP, we have subfrom already bind to <level2>   $.level1.level2, but then could we access name inside it? and how?

<subfrom bind = "$.level1.level2">     <textfield bind = "----$.??????.name----"> </textfield>     <textfield bind = "$.data"> </textfield></subfrom>

thanks in advance,
