Procedure

1. Go to the ditac_install_dir/xsl/common/messages/ directory.

   ~$ cd /opt/ditac/xsl/common/messages/

2. Copy en.xml to pt.xml.
   Note that "pt" is the ISO 639-1 two-letter code of the Portuguese language.

   Country variants of a language are supported too. Example: pt-BR (Brazilian Portuguese). However, when this is the case, make sure that the name of the file containing your messages use lower-case characters. Example: pt-br.xml should be fine, while pt-BR.xml or pt_br.xml would not work.

   /opt/ditac/xsl/common/messages$ cp en.xml pt.xml

3. Open pt.xml in a text or XML editor and translate to Portuguese all the messages found in this file.

   <?xml version="1.0" encoding="UTF-8"?>
   <messages xml:lang="pt">
     <!-- Task sections -->
     <message name="prereq">Pré-requisito</message>
     ...

   For some languages, like CJK languages, you'll have to insert variable %{N} in the localized text corresponding to numbered elements (Chapter, Appendix, Table, Figure, etc). This variable is replaced by the number of the element.

   Japanese example: excerpts of a possible ditac_install_dir/xsl/common/messages/ja.xml:

   <message name="chapter">第%{N}章</message>

   For the first chapter of the document, this gives "第1章", which means "The 1 Chapter".
4. Open ditac_install_dir/xsl/common/commonUtil.xsl in a text or XML editor and add string 'pt' at the end of the messageFileNames list:

   <!-- localize ========================================================== -->
   
   <xsl:param name="messageFileNames" select="'en', 'fr', 'de', 'es', 'pt'"/>

5. When done, please send us (ditac-support@xmlmind.com) your translation (e.g. pt.xml) so we can add your contribution to the distribution of XMLmind DITA Converter.
