Nested square brackets are rarely necessary (as David of course knows), 
though quite useful in this explanatory example:

text()[ancestor::label/@title='xxx'] will work as well, as will (as someone 
else noted) label[@title='xxx']//text().  In theory, there shouldn't be a 
difference in speed of the implementations of one or the other, but I'm not 
sure how true that is in practice.
