set ditakeycontext=URI

This option contains the URI of the source of key definitions for key references in the current document. You can also set this option explicitly or Arbortext Editor sets it automatically in some cases. For example, when a user opens a topic from within a map, Arbortext Editor automatically sets that topic's ditakeycontext value to the URI of the map. The elements in the topic with keyref attributes referencing keys will then use the key definitions defined in that map.

This map is also used, in addition to the maps set in the ditakeybaselist preference, to populate the Keyref field on the various Resource Manager tabs and versions. This option has document scope and does not persist across sessions.
