ORA-54526: multi or composite geometry mustbe decomposed before extraction

Cause: The extraction could not beperformed because the multi or composite

geometry must first be decomposed into simple geometries(with or without inner

geometries). The multi or composite geometry had a gtypeof GTYPE_

MULTISOLID, GTYPE_MULTISURFACE, GTYPE_MULTICURVE, GTYPE_

MULTIPOINT, or GTYPE_COLLECTION, or the geometry was aline string.

Action: Use the MULTICOMP_TOSIMPLEparameter to element extractor to

decompose the multi or composite geometry to a simplegeometry.
