I'm not sure what the alternative should be for, but one thing which in my 
opinion complicates the xpointer() scheme is the Range extensions it brings 
to the otherwise vanilla XPath. The 3rd party scheme xpath1()[1], allowing 
selections to be done with plain XPath 1.0, is in my opinion a nice 
light-weight alternative to xpointer() which nevertheless is useful. Mozilla 
implements it, I was told.

In my opinion, a problem with it is that it does not use a namespace, which 
the XPointer Framework requires 3rd party schemes to do. One approach to 
solve that, if it is considered a problem, is to lobby for having W3C host 
the scheme. I think that is a good idea, because W3C would be standardizing 
current practice; embrace a way a specification conflict; and the 
specification has sensible content, it wouldn't require much development 
except running the W3C machinery..

Merely ventilating the idea.

PS. There's a newly created XPointer implementation in KDE; it implements 
everything except the xpointer() scheme:
