- list Attribute → Enumeration Literal
as screenshot, the Enumeration should be a Class with<<enumeration>>stereotype
Then, you retrieve the enumeration literals from Attribute.type :
<ModelElementPropertyConditionChecker property="type">
<Conditions>
<ValueChecker property="modelType" value="Class"/>
<ValueChecker property="stereotypes" value="enumeration"/>
<IterationBlockConditionChecker modelType="EnumerationLiteral"/>
</Conditions>
<Text> : [</Text>
<ModelElementProperty property="type">
<IterationBlock modelType="EnumerationLiteral" ignoreLastSeparator="true">
<Property property="name"/>
<Text>, </Text>
</IterationBlock>
</ModelElementProperty>
<Text>]</Text>
</ModelElementPropertyConditionChecker>
