contrib/xml2 and xml type

Assuming a working xml type, what do you think the future of the 
contrib/xml2 module should be?

At the moment, I'd imagine that we add duplicate versions of most 
functions, where appropriate, that use the xml type instead of the text 
type.  Perhaps we should supply two sets of SQL files, so that users 
have the choice of using the "legacy" versions or the "type-safe" 
versions.  Anything else?

(I understand that some people are researching GIN-optimized XPath 
access to XML data, but that is really a bit further out.)
