[UIMA] How to get the element type from a TypeSystem Object

[Manuel Fiorelli]

I need to get the element type of a feature from a TypeSystem object. I
didn't find any method in the Feature interface. However, when I have a
definition like that

<featureDescription>
<name>foo</name>
<rangeTypeName>uima.cas.FSArray</rangeType>
<elementType>uima.cas.Boolean</elementType>
</featureDescription>

then, foo.getRange().getComponentType() gives uima.cas.Boolean, as I
expected.
But, if the range type is uima.cas.FSList I know no way to get the element
type.

I tried the code

TypeSystemUtil.feature2FeatureDescription(base_foo).getElementType()

but it returns null.
