This parameter specifies the URI of a XML document that describes text translations (and other locale-specific information) that is needed by the stylesheet to process the DocBook document.

The text translations pointed to by this parameter always override the default text translations (from the internal parameter localization-file). If a particular translation is not present here, the corresponding default translation is used as a fallback.

This parameter is primarily for changing certain punctuation characters used in formatting the source document. The settings for punctuation characters are often specific to the source document, but can also be dependent on the locale.

To not use custom text translations, leave this parameter as the empty string.
