> Currently in HQL queries, the translator disables inclusion of filters on subqueries.  Mainly, this was due to the fact that the parameter binding code gets confused because the parameters end up "out of expected order" (filter parameters are always expected to be the first bind points within the resulting SQL query).
> However, it is definitely possible to have the translator deal with this correctly.  This will require changes to JoinProcessor, Loader, QueryLoader, and (possibly) FromElementFactory to make use of the ParameterSpecification stuff currently tracked on HqlSqlWalker.
> Then, we should allow a (SF-scoped) config option as to whether filters should be applied to subqueries (false by default).
