I am learning the schema of Adobe Campaign V7 . I find the dbEnum keyword in the neo:recipient as the follow.
<!-- Attribute: Preferred Channel -->
<attribute dbEnum="channel" desc="Preferred communication channel" label="Preferred channel"
length="15" name="preferredChannel" sqlname="sPreferredChannel" type="string"/>
And I chekc the guide of dbEnum :dbEnum (string): receives the internal name of a "closed" enumeration. The enumeration values must be defined in the <srcSchema>.
My question is:
(1) I can not find the define of dbEnum="channel" in the schema. Where it was defined?
(2) How could I extends value for the enumeration dbEnum="channel" ?
That is what I want. Very professional answer.
