Probably you have not fully understood (catching that was difficult to 
me) that what you are assigning to the variable "data" is the node-set 
specified by ".".

Then you are selecting:

all (*) the attributes (@) of the node contained in $data whose name() 
equals the dbcolumn attribute (@) of current() node.

current() node is the way you have to refer to the node that was current 
"outside the [ ]", as referring to "." inside the [ ] you mean the node 
you are testing for inclusion on the result.

HTH.
