He suggested that an implementation or interpretation guide be prepared to address these issues. The expert of OICA welcomed this initiative and pointed out that OICA had started compiling its own list of ambiguities. Following an exchange of views, GRB invited the experts from France, ISO and OICA to prepare a consolidated list of such issues for GRB review and envisaged that further work could be pursued in the framework of a small drafting group.
