Adds an attribute to any cvtype, which will cause keywords to expand on the specified cvtype. Keyword expansion normally occurs at check out, but with this option will occur at checkin. You must be a database administrator to use this option.
To force keyword expansion at checkin for objects of a certain type, add the expand_on_checkin attribute to any type. For example, to enable it for all text type objects, add the expand_on_checkin attribute to the ascii cvtype; this value will be inherited by all objects in the ascii hierarchy.
The default for expand_on_checkin is unset. This option is boolean, so it must be set to either TRUE or FALSE.
An example of how to use this for the ascii type is
$ ccm set role ccm_admin
$ ccm query -t cvtype -n ascii
$ ccm attr -c expand_on_checkin -t boolean -v TRUE @1
