Yes. Or even /document[1]/head[1]/title[1]; though that's second-guessing
the optimization that the processor does.

Actually with Saxon, assuming there is a single <title> element in the
document, //title will be a lot more expensive than /document/head/title the
first time it is used, but it will be slightly cheaper on the second and
subsequent occasions; but on the other hand, if you are going to use it
repeatedly, it would be better to use a global variable.
