I have a use case of arrays of nested Sequences.
I use the following for multipolygons
http://iridl.ldeo.columbia.edu/SOURCES/.NOAA/.NCDC/.CIRS/.ClimateDivision/dods.dds
In particular,
Sequence { Sequence { Sequence { Float64 lat; Float64 lon; } ring; } polygon; } location[IDIV = 344];
is a set of multipolygons, one for IDIV, a multi-polygon consisting of a number of closed polygons, a closed polygon consists of an outer ring and possibly a number of inner rings (cutouts).
The index is important, because it connects to the rest of the data, i.e. time series for each division stored in a square array. The division has an associated shape, the multi-polygon, which geolocates the time series.
