+A domain coordinator determines whether External Tools which support the LTI 
+(Learning Tool Interoperability) standard should be available in each course
+type, or in specific course(s), and also whether definition and configuration
+of such tools are permitted within your course.

+External Tools may have been defined at a domain level for use in your course, 
+and if so, the options which can be set when including one of the available tools 
+within a course or community, will also have been set in the domain.
 
 The full range of options which may be available to the Coordinator in the course
 or community are:
 
 \begin{itemize}
