Indexable	This interface should be implemented by all basic types to be used as keys in a value index.
SystemTask	Interface to be implemented by tasks used for system maintenance.
TermMatcher	Implementations of this interface can be passed to method TextSearchEngine.getNodes(XQueryContext context, DocumentSet docs, NodeSet contextSet, int axis, QName qname, TermMatcher matcher, CharSequence startTerm) to check if an index entry matches a given search term.
UpdateListener
ValueIndexKeyFactory	Factory for Keys for Value Indices; provides through serialize() the persistant storage key.
