Return the text portion of the fullElementName representing a group. That means that this should only return text that is part of the fullElementName and not look up new IDs or do much of anything fancy. This method is used by the resolver to decide which portion of a fully- qualified element name is the group name. It will compare whatever comes back with the actual group names and aliases in the query, which is why it is important not to introduce new metadata here. Also, returning null indicates that no portion of the fullElementName is a group name - that is ok as it will be resolved as an ambiguous element.
