Lack of interest Non-scalar values in xen:set

[simbolo]

For example I want to pass an array value to a template:

<xen:include template="widgetportal_widget_carousel_edit_item" >
    <xen:set var="$item.carousel_id">0</xen:set>
</xen:include>

I can't do that as it responds with:

The following error occurred:

Line 28: Invalid template include variable assignment specified. Only scalar variable names may be assigned.

Is it possible to add the ability to pass non scalar values?
