Description

When "in" is an XMLInputSource for an analysis engine descriptor, the following returns null if it's an aggregate AE:

UIMAFramework.
getXMLParser().
parseAnalysisEngineDescription(in).
getAnalysisEngineMetaData().
getTypeSystem()

Though I understand the reason for this (an aggregate AE's type system is just the union of its delegates' type systems, and isn't described explicitly in the aggregate descriptor), it would be more convenient if it worked for aggregates too.

At the least, the documentation should reflect this limitation.
