Aha! I'd been assuming the solution was to provide url-encode() and
url-decode() methods. 

If we're going to provide an extensible list of alternative methods,
then maybe we need a way of expressing and implementing the rules
concerned. Possibly we start with phrasing similar to that for HTML

	"The html output method may output a character using a character entity
reference, if one is defined for it in the version of HTML that the
output method is using."

for the character entities; and something rather like a transform for
specifying which elements or attributes get their text content encoded;
and finshing up with an exsl:<myOutput>-encode() function for actually
encoding them.
