Export xmi

[Chance]

Hopefully one of you can point me in the right direction.

I am using VS 2010 Ultimate as my software architecture tool. Unfortunately, the PM's and BA's all do not have Visual Studio installed nor should they have to. I would like to have them create the User Stories, Activity Diagrams, etc... in Visio and then let me import them into Visual Studio to create the rest of the models and assign work items off of.

I have been able to export Visio UML diagrams to an XMI file following the directions here http://modeling-languages.com/blog/content/microsoft-visio-uml-xmi-export. When I try to import this XMI file into Visual Studio, it tells me that it is the incorrect version of XMI, it can only import 2.1.

I have searched for an answer to this, but cannot find out how to export to XMI 2.1, can anyone help me with this?

Thanks
Jeff
