This is still constructing the serialized form as a string, which gives me the flinch.  Experience says this is not how I lower the maintenance cost of the code.

Having my own XPath function library introduces all sorts of maintenance and portability problems customers are generally savvy enough to spot and complain about. (and my employer is _certainly_ savvy enough to spot and complain about!)
