validate regex inside XML synthetic.xml

I have the following synthetic.xml file and need to validate user input using regex.

<synthetic xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns="http://www.xebialabs.com/deployit/synthetic"
           xsi:schemaLocation="http://www.xebialabs.com/deployit/synthetic synthetic.xsd">
    
        <type type="keyCreation.Streams" extends="xlrelease.PythonScript">
            <property name="taskColor" hidden="true" default="#00b0ff" />
            <property name="scriptLocation" hidden="true" default="tasks/key_creation.py"/>
    
            <property name="PACKAGE_NAME" label="Package Name" category="input"  description="Package NAME"  required="true"/>
       </type>
</synthetic>

I need to evaluate the package_name as follows in the xml file regex validation of the user input

"^(data|products|etl)-[0-9a-z-]+$"

How can i add regex validation to the property name = PACKAGE_NAME
