Variable binding for a projection

Question

The 11.14. Projection Variables example shows how to bind a collection
element variable in the query filter for enabling its projection :
Query query = pm.newQuery (Magazine.class, "price < 5 "
+ "&& coverArticle.subtitles.contains (ttl)");
query.setResult ("ttl.substring (0, 3)");
It seems to me that :
such a variable binding has nothing to do in the filter, as it is not usedin any predicate
it would be better to extend the variable declarations, enabling to specifysuch a variable binding, with the two following syntax proposals (preference
descending) :
1) String variables = "coverArticle.subtitles(ttl)"
2) String variables = "String ttl elementof coverArticle.subtitles"
What do you think ?
Regards.

Patrice-
Could you expand on this a bit? I'm afraid I don't really understand
what you are trying to convey.
