which might result in a sequence of more than one element.

Wendell,

I dont see this as paranoia, because such stuff happens! Do you agree that
another option to force the resulting sequence to have only one element would
be

normalize-space((..//image-size)[1])

But I agree that the use of descendant:: is much clearer, especially to people
who (have to) read this bit of code later.
