How to setup links integrity?

I have these 2 schemas:

<srcSchema entitySchema="xtk:srcSchema" img="xtk:schema.png" label="Consent Log"
           name="consentLog" namespace="li" xtkschema="xtk:srcSchema">
 <element autopk="true" label="Consent Log" name="consentLog">
    <attribute label="Customer Id" length="36" name="customerId" type="string"/>
    <element label="Customer" name="customer" target="li:customer" type="link">
      <join xpath-dst="@customerId" xpath-src="@customerId"/>
    </element>
    <element label="Consent" name="consent" target="li:consent" type="link"/>
  </element>
</srcSchema>

<srcSchema entitySchema="xtk:srcSchema" img="xtk:schema.png" label="Trial Registration Consent"
           name="trialRegistrationConsent" namespace="li" xtkschema="xtk:srcSchema">
  <element autopk="true" label="Trial Registration Consent" name="trialRegistrationConsent">
    <element label="Consent Log" name="consentLog" revCardinality="single" revIntegrity="own"
             target="li:consentLog" type="link"/>
    <element label="Trial Registration" name="trialRegistration" target="li:trialRegistration"
             type="link"/>
  </element>
</srcSchema>

What I want from them is the following: If someone (Workflow, User manually, any JS code) will delete item from li:consentLog I want corresponding item to be deleted from li:trialRegistrationConsent.

This doc (https://docs.campaign.adobe.com/doc/AC/en/CFG_Schema_Reference_Database_mapping.html#Links-_relation_between_tables ) says I need revIntegrity to be "own". But it doesn't work or I don't understand the doc. Help pls.
