Here are the stops I can see for the Exhibition Centre - note that  
this does include the railway station that is managed nationally so  
could well be missing from the West Midlands data (but is part of the  
offer from the DfT/Traveline to OSM)

Bickenhill Lane (adj)
Bickenhill Lane (opp)
Birmingham International Rail Station      (this is the station itself)
Birmingham International Station (Stop NA)
Birmingham International Station (Stop NB)
Birmingham International Station (Stop SA)
Birmingham International Station (Stop SB)
Birmingham International Station
Cottages
Elmdon Trading Estate (adj)

And these are for Birmingham Airport which is very close

Birmingham Airport Bus Terminal (Stand  H                     )
Birmingham Airport Bus Terminal (Stand J)
Birmingham Airport Bus Terminal (Stand K)
Birmingham Airport Bus Terminal (Stand L)
Birmingham Airport Bus Terminal (Stand M)
Birmingham Airport Skytrain
Birmingham International Airport Terminal 1
Birmingham International Airport Terminal 2
Birmingham International Airport
Cottages
Marston Green

The Birmingham Airport stops are 'offstreet', however the exhibition  
centre ones are 'onstreet'

Personally I suggest we aim to import all the Stop Points in the first  
pass (be they onstreet/offstreet or be they taxi ranks/bus stops or  
railway station entrances). I say that because they are all simple  
point features and give that there is some variation about what is  
classed as onstreet or offstreet it will be confusing to do otherwise.
