Last night I realized another reason to deprecate and eliminate the 
last four of these constructors. Each one of them creates anew 
Builder object. This is potentially quite an expensive operation. 
Whether it's expensive relative to compiling the stylesheet and 
running the transform depends on local circumstances, but in at least 
some circumstances it makes a lot more sense to reuse a builder if 
possible, rather than creating a new underlying XMLReader for each 
separate document.
