Current status of XLink

What is the current status of Xlink?

I have googled around quite a bit but only found information that is
over 2 years old...  Has anyone done anything with it?

I ask because I have a custom independent linking solution, that
potentially has to process Xlinks as well.  I suspect the requirement
has come from a manager, rather than a developer, who would like a
one-to-many indpendent linking ability and read the 2 year old
evangelising on the subject.

Where can I find some more recent information?

Is xlink/xpointer just slow to take off, or is it already dead?

Are there any xpointer-to-xpath converters? :)

thanks
