In the Schema Documentation, it states that SubTitle is "Not applicable to listings in US eBay Motors passenger vehicle, motorcycle, and "other vehicle" categories or to listings in CA eBay Motors passenger vehicle and motorcycle categories".
However, I am getting an error trying to list a Motors item indicating that the SubTitle attribute is required.
How do I specify a SubTitle attribute in my motors listing?
Specifying SubTitle, DepositAmount, and DepositType for Motors (not including Parts&Accessories) requires manually inserting the attributes into the request.
