   I've looked at all all uses for `replaceAll`, and I don't see any uses that 
could contain a back slash or a dollar sign. All instances use a hardcoded 
replacement values, or are now properly escaped with this change.
   
   The one exception was for code that used to handle `dfdl:outputNewLine`, 
which could theoretically contain a dollar sign, but that is dead code. That 
property is now handled without `replaceAll`. I've just removed that function 
to remove the possibility of every using it with bad input.
