Namespaces are only ever attached to elements.  They are never 
attached to attributes.  Attributes use the namespaces that are 
attached to elements in the ancestry.

Your "real work" results are acceptable and appropriate, I see nothing wrong.

Probably that attributes use namespaces attached to elements in the ancestry.

And they are equivalent, provided that the XLink namespaces is 
declared in the ancestry.

If you want the xlink:href= attribute absent in the given element, 
then you have to attach it to one of the elements in the 
ancestry.  Most folks just go ahead and attach all desired namespace 
nodes to the document element so that they are in scope of all 
elements of the document and never need to be redeclared.

I hope this helps.
