Composite Geometry Builders
Geometry builders that can integrate another geometry into their own are calledcomposite geometry builders, those that do not are callednon-composite. Note that the composite, non-composite qualifiers do not refer to the type of geometry that the builder constructs, instead, they refer to whether or not the builder is capable of integrating another geometry into its own.
Usually, the builders that construct aggregate geometries are composite geometry builders. One can envisage a custom non-composite geometry builder that builds an aggregate geometry. For example, if a multi-point feature in the input XML document is defined to be something like:
2.3,34.9 445.4,34.34 23.35,345.453
A custom geometry builder used solely to build an aggregate of point features out of the
