Hi Sam,
The Multipolygon wiki page [1] explains it better than I could do:
The intended use of multipolygons is this:
* Tags describing the multipolygon should go on the outer way.
* If the inner way represents something in itself (e.g. a forest
with a hole where the hole is a lake), then the inner way may be
tagged as such.
* Otherwise the inner way(s) should be left untagged.
* The direction of the ways does not matter.
* If there is no role given outer is assumed, this makes defining
boundaries easier as no explicit outer role is needed for all the
elements (which can be in the hundreds). But to avoid ambiguity the
role should be set in case there are inner elements.
* "name" tags of the relation are rendered by mapnik but not by
osmarender.
