No, because the SPServices Cascading dropdowns functions on list forms.  To my knowledge, you can't specify metadata before creating a document.  You could require check in/out on the document library to force an item be checked in before being available and this would let you use the SPServices cascading dropdowns since that's effectively an editform.

I'm wondering if there's a way to extend the document information panel in Word to account for something like that.

I am facing a very puzzling aspect of the REST API of Magento. Seemingly, the GET /Orders response does not return any date. This can't be right, sales orders are dated. 

What am I missing here?
