At 07 Aug 2001 I posted patches for
src/org/apache/cocoon/transformation/I18nTransformer.java
and
xdocs/i18n-transformer.xml
I have no access to cvs, thats why I post an ordinary diff -u
before changes:
version of xdocs/i18n-transformer.xml: 1.6
version of src/org/apache/cocoon/transformation/I18nTransformer.java:
1.14
Regards,
Michael
