Upgrade to JSTL 1.1.2

Question

Hello,
I have upgraded my jstl and standard libs from 1.0.6 to 1.1.2 version.
Using 1.0.6 I had many "c_rt" tags into my jsp pages.
So I'd like to know if I can still use those tags, conserving the old c_rt include, or if I have to remove this include and replace all my c_rt tags with c tags (which would implie more work):
To be more explicit :
Can I have those includes (new one with old one):
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@taglib uri="http://java.sun.com/jstl/core_rt" prefix="c_rt"%>
or should I only have the new one :
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
I think the the c_rt compatibility is assumed in 1.1.2 version but I'd like to have a confirmation from you.
Thank you for your answers.

Answer 1

From my understanding of the system it WILL work unchanged.
But to my mind it would be better if you replaced all the c_rt tags with c tags, because under JSTL1.1 the standard tag accepts both ${expr} and <%= expr %>
Surely it is relatively easy to do with a global search and replace?
