When a .docx is uploaded, the list of properties that appears on the Share preview screen is different than I normally see for a .doc.  I upload a .doc and then a .docx – both documents are type cm:content, why the difference?  Is the extractor capturing more data for the docx?  
In the docx property list, there are elements present from the lockable aspect, but I don’t see the lockable aspect defined in share-form-config.xml.     Why do they still appear? 
For a docx, the following properties appear:
