How about adding a mode attribute to search_replace like what 
environment has - that allows two options replace or prepend?  Replace 
would act like a simple sed command.  Prepend would do what I want it to 
do.  The new DTD would look like this:

!ELEMENT search_replace (file, find, replace)
!ATTLIST search_replace
           base           CDATA #IMPLIED
           mode           (replace | prepend) "replace"
