I would like to add a Level-Of-Detail value to the spatial types. Without this it is impossible.

In fact, I would like to compose types with compound type as a subfield. Is this possible?

> A few small changes to the AbstractSubTypeFieldType class to allow users to define distinct field types for each subfield.  This enables us to define complex data types in the schema.
> For example, we have our own subclass of the CoordinateFieldType called TemporalCoverage where we store a start and end date for an event but now we can store a name for the event as well.
> <fieldType name="temporal" class="uk.ac.edina.solr.schema.TemporalCoverage" dimension="3" subFieldSuffix="_ti,_ti,_s"/>
> In this example, the start and end dates get stored as trie-coded integer subfields and the description as a string subfield.
