Alain Reguera Delgado e54180
#   of translation markers and their related expansion. As convention,
Alain Reguera Delgado e54180
#   translation markers must be set inside source files (e.g.,
Alain Reguera Delgado e54180
#   Docbook, Svg, etc.) and expanded inside temporal instances used to
Alain Reguera Delgado e54180
#   produce final contents.
