Server: Vista2.0(?) | Client: ?(?)

Hi,

I am a bit confused on the status of QTI-version-compliance of the
different bits of Vista 2.0. Currently I am importing as part of a
whole course questions. But for example the size of the FIB-box is
discarded and defaults to 20. What parts of QTI is supported as part
of importing a template, and is that version 1.1?
In addition the Vista 2.0 Web services do mention in chapter 7, QTI
version 1.2 and the examples are radical different than in the
migration quide, but do resemble more the Vista edit question
interface.
We are in search of a fully automated content upload since we have
hundreds of questions and more to come.

Does anyone have any experience using the webservices SDK?

Thanks in advance,
Cees and Kor
