Serialization options are a little sparse

[fidothe]

Currently we just do a very naive call to Saxon's serialisation API to return an XML string. We should see what Nokogiri has by way of a serialisation API and implemnent it, if it's not too odd or tied to objects we don't have

pinging @pobocks - any thoughts / things you want?

Hmmmm... I'm not sure I have feelings re: serialization - thus far, XML string works for me. I'll let you know if I can think of anything...
