Used in a callable block such as a <macro> or <view> to return data.

If you enclose any data setter tag (<int>, <str>, <list> etc.) in the return block, the result will be returned. For example, the following macro will return a list of three items:

<macro libname="get_crew">
    <return>
        <list>
            <str>John</str>
            <str>Scorpius</str>
            <str>Rygel</str>
        </list>
    </return>
</macro>

Alternatively, you may use the value attribute to return the result of an expression. The following code is equivalent to the above:

<macro libname="get_crew">
    <return value="['John', 'Scorpius', 'Rygel']" />
</macro>
