New VAT configuration for Europe

Hi,
Does anybody have documentation regarding the OTM VAT Outcomes?
I set up the VAT config, Tax Type = 'European VAT',
For my tests, I use two country codes: ITA (Italy) and GBR (Grande Bretagne),
I set only the GBR as EU Member.
Service provider Country is ITA (not EU Member).
Have an order release (Source location country ITA, and destination GBR).
When I calculate the vat, OTM selects the IMPORT_LOCAL_SERVPROV as VAT Outcome.
I don't get it. Why IMPORT?
And how do we consider a Foreign or Local servprov?
If I new the OTM logic behind all these Outcomes, I would maybe understand.
