The search path for data types includes language-dependent locations. The desktop uses the value of LANG to determine the locations searched for data type definitions.
Localized data type definitions must be placed in the proper language-dependent directories along the actions search path.
The default search path is:
Personal actions: HomeDirectory/.dt/types
System-wide actions: /etc/dt/appconfig/types/language
Built-in actions: /usr/dt/appconfig/types/language
