Description:
tool for translating XML documents with PO files
ITS Tool allows you to translate your XML documents with PO files, using rules from the W3C Internationalization Tag Set (ITS) to determine what to translate and how to separate it into PO file messages. . ITS Tool is designed to make XML documents translatable through PO files by applying standard ITS rules, as well as extension rules specific to ITS Tool. ITS also provides an industry standard way for authors to override translation information in their documents, such as whether a particular element should be translated.
