greywind commented on JBRULES-1440:
-----------------------------------

What I would like to be able to do is:

package org.drools.entity

template ISIN
    String Identifier
end    

template Identifiers
    ISIN ISIN
end

template Settlement
    String InstrumentType
    String InstrumentName
    Identifiers Identifiers
end

rule "TestEntity"
dialect "mvel"
    when
        $s : Settlement(InstrumentType == "BOND", name : InstrumentName, id : Identifiers.ISIN.Identifier)
    then
        
        System.out.println("Found: " + name + ", " + id);
end

I want to use a template definition as a type in another template.
