.trim() will remove leading and trailing (only) 'whitespace' which means 
tabs, newlines, and spaces.  In some objects we do not run the cleaning 
procedure at all (xquery statements come to mind) but it would be simple 
enough to turn this feature on.  If anyone could think of a list of 
where trimming absolutely should be done let me know and I can start to 
fix the classes.


Cleaning any whitespace/newlines out of the middle of text element is a 
little more challenging (we would need to use the regex classes) but 
this also could also alter the meaning of what was sent (again, xpath or 
xquery statements).
