It turns out that it's a very difficult decision, and in the end,
someone's life has to end up being harder.

To make this really useful, however, we should add equals(), intern(),
and hashCode() methods, and that leads to a different (and trickier)
should equals() and hashCode() consider the prefix, or not? People
will get really surprising results if
{"http://www.w3.org/1999/xhtml", "a", ""}
equals()
{"http://www.w3.org/1999/xhtml", "a", "html"}
but it is counterintuitive that the two are not equal from a normal
processing perspective. Nasty business, really.
All the best,
