> If you want we can change that by having an attribute at the ruleset level called match_multiple_rules: True|False with the default being False and on the Drools side Mario can use that to implement the Drools behavior which is inherently to match with multiple rules and be like facts.

Acceptance Criteria:

Introduce ruleset level attribute
match_multiple_rules: True|False with the default being False

If true, events can match multiple rules like facts.
