Multipolygon overlapping issue

MultiPolygon doesn't support overlapping polygons:

2.1.12 MultiPolygon
A MultiPolygon is a MultiSurface whose elements are Polygons..
The assertions for MultiPolygons are :
- The interiors of 2 Polygons that are elements of a MultiPolygon may not intersect.
∀ M ∈ MultiPolygon, ∀ Pi, Pj ∈ M.Geometries(), i≠j, Interior(Pi) ∩ Interior(Pj) = ∅- The Boundaries of any 2 Polygons that are elements of a MultiPolygon may not ‘cross’ and >may touch
at only a finite number of points. (Note that crossing is prevented by assertion 1 above).
∀ M ∈ MultiPolygon, ∀ Pi, Pj ∈ M.Geometries(), ∀ ci ∈ Pi.Boundaries(), cj ∈ Pj.Boundaries()
ci ∩ cj = {p1, ….., pk | pi ∈ Point, 1 <= i <= k}- A MultiPolygon is defined as topologically closed.
- A MultiPolygon may not have cut lines, spikes or punctures, a MultiPolygon is a Regular, >Closed point
set:
∀ M ∈ MultiPolygon, M = Closure(Interior(M))- The interior of a MultiPolygon with more than 1 Polygon is not connected, the number of >connected
components of the interior of a MultiPolygon is equal to the number of Polygons in the >MultiPolygon
This issue happens as I try to merge Polygons into a single MultiPolygon. That way I make one request and have multiple responses. As I make lots of requests, this hackish way allows me to reduce the number of requests thus gaining process time.
I would suggest to keep it like that to respect OCJ standard, but maybe add support for an official ‘multi-params’ support.
I would guess that support would be allowed by taking an array as parameter instead of a single object.
@zephylac sorry for being very dormant lately. This approach with multi-params
sounds just fine
