HQLfind instances of a class that have all of a given list of keys in its composite-map-key

Question

<classname="Source" table="source">
  <component name="map" access="field">
    <map name="parameters" access="field" table="parameters"
            cascade="all-delete-orphan" lazy="true" sort="natural">
            <key column="owning_source" not-null="true"
                 foreign-key="source_params"/>
            <composite-map-key class="Key">
                <key-property name="namespace" column="namekey" length="100" access="field"/>
                <key-property name="key" column="subkey" length="100" access="field"/>
                <key-property name="index" column="idkey" access="field"/>
            </composite-map-key>
            <element type="string" column="value" length="512"/>
    </map>
  </component>
</class>

I am trying to figure the HQL that, given a List will find all the source classes that have all of the keys in the list as parameters.

Something like (pseudo):

select s from Source as s where all index(s.map.parameters) in :keylist

Thanks
