/**
 * This extends a list that is itself a property (with key mapKey).  It does not have any
 * container element.
 *
 * This could also be achieved with
 * new ChildSingletonMapDefinitionParser("properties")
 * .registerPreProcessor(new AddAttribute(MapEntryCombiner.KEY, "soap11Transports"))
 * .addCollection(MapEntryCombiner.VALUE)
 * .addCollection("properties");
 * I think, but the following avoids worries about special attribute names.
