Implicit format item modifier added.
          #2521   Compile-time warning
          Implicit format item modifier added.
Additional Information
 The 'z' modifier is automatically added to the '%v' format item in
TRANSLATE rules.
Explanation
When CDATA attributes are emitted with the '%v' format item, they
are normally subject to processing by TRANSLATE rules.  When they are
emitted inside TRANSLATE rules, no further TRANSLATE-rule processing
can be done on them.  This is done by putting the z modifier on the
item.
