First, eliminate XSL-FO from the equation. Is the XSLT output different 
from the two processors?

Unwanted whitespace in XSLT output comes from one of three places:

(a) whitespace being copied from the source document

(b) whitespace copied from the stylesheet

(c) indentation added by the serializer

First see what the extra whitespace looks like. Is it adjacent to 
non-whitespace text. If so, where does that text come from? Is it in 
mixed content elements or in element-only content? Does it include 
newline characters? Is it the entire content of an element? This 
information will often lead you to identify one of the three causes 
above as the most likely.

The fact that you're getting different output from different processors 
is another clue. It tends to suggest a difference in parsing or 
serialization behaviour rather than in the transformation proper.
