You can do it with something like:

%dw 2.0
output application/xml
ns ns0 http://www.demandware.com/xml/impex/order/2006-10-31
var obj = payload.Envelope.Body.notifications.Notification.sObject
var customAttrs = obj -- ["order-status", "order-no"]
---
{
    orders @(xmlns: ns0): {
        order @("order-no": obj."order-no"): {
            (status: obj."order-status") if obj."order-status" == "CANCELLED"
        },
        "custom-attributes": customAttrs mapObject ((value, key) -> {
            "custom-attribute" @(id: "$key"): value
        })
    }
}
