According to the 3.2 spec (ver. 20091207), Section 2.14 - Asynchronous Queries: 

"A query object is created and made active by calling
void BeginQuery( enum target, uint id );
target indicates the type of query to be performed; valid values of target are defined in subsequent sections. If id is an unused query object name, the name is marked as used and associated with a new query object of the type specified by target.  Otherwise id must be the name of an existing query object of that type.  BeginQuery fails and an INVALID_OPERATION error is generated if id is not
a name returned from a previous call to GenQueries, or if such a name has since
been deleted with DeleteQueries."

However, the following 2 lines don't seem to be compatible:

1) "If id is an unused query object name, the name is marked
as used and associated with a new query object of the type specified by target"

2) "BeginQuery fails and an INVALID_OPERATION error is generated if id is not
a name returned from a previous call to GenQueries, or if such a name has since
been deleted with DeleteQueries"

I assume the first line should be removed, since application-generated object names have been deprecated.
