Daniel - I think you missed Prakash's point. It's not that he wants 
AttributeSelector to return a generic DOM node, it's that he wants it 
to be able to use an arbitrary node as the root for some data, which 
may be a single value or may be mixed content. True, in the standard 
there are no datatypes that support this, but you can write a custom 
datatype (and custom functions) that do. When you do so, you can't 
select it with an AttributeSelector since that mechanism is restricted 
to work only with attributes/text/etc.

Basically, it's a shame that you need to write a new function that acts 
just like AttributeSelector for any new datatype you invent that is 
represented by mixed content in a DOM tree. On this point I agree.
