At the moment, the <result> field has an attribute aggregation-status: "Boolean flag indicating whether the data in the result set are suitable for aggregation."

I propose to remove this attribute:

- It is defined at the <result> level. There can be multiple <indicator> elements in a <result>, and some may be suitable for aggregation, while others are not. Would I then set this flag to "true" (some data in the result set is suitable for aggregation) or to "false" (not all the data is suitable for aggregation)?

- It doesn't let me specify over which dimensions it can be aggregated. "Households reached" can usually be aggregated over regions, but not over time spans.
