Excluding both WMFParser and EMFParser causes wmf instances NOT to appear at all

I was attempting to exclude embedded wmf and emf files from being parsed, but I noticed that when I do so, only instances of EMF files are noted by Tika in the returned /rmeta/text

As an experiment I created two tika-config.xml files. The first excludes only the WMFParser, and when my MSWord source doc is processed I see lines like this, as expected:

"Content-Type":"image/wmf","X-Parsed-By":["org.apache.tika.parser.CompositeParser","org.apache.tika.parser.EmptyParser"]

And there are the EMF files that were found and parsed by the EMFParser:

"Content-Type":"image/emf","X-Parsed-By":["org.apache.tika.parser.CompositeParser","org.apache.tika.parser.DefaultParser","org.apache.tika.parser.microsoft.EMFParser"]

A problem arises though when I try to exclude WMFParser AND EMFParser. Suddenly any WMF instances have disappeared and only EMF instances are shown as being handled by the EmptyParser. 

"Content-Type":"image/emf","X-Parsed-By":["org.apache.tika.parser.CompositeParser","org.apache.tika.parser.EmptyParser"]

I think in the 2nd case BOTH types should be shown as being handled by the EmptyParser. I still want to know that the WMF files are in the container even though I'm not parsing them.

P.S. For whatever reason I can't upload the original Word doc that I'm testing with. Jira won't allow me.
