Filter configuration for properties for graphical elements (Office filter)

What steps will reproduce the problem?
1. Take a document (docx/pptx) containing a graphic/smart-art/text field/shape, 
etc.
2. Extract the document

What is the expected output? What do you see instead?
Expected output: Only the "real text" will be extracted as translatable text.

Current output: The extracted xlf document also contains properties for 
graphical elements as translatable texts (e.g. Textfeld 1, Grafik 2, ...)
They are all from the name attribute of wp:docPr elements

What version of the product are you using? On what operating system?
Okapi version: M27, Operating System: Windows 7 Enterprise
