How do I add a validator to a build in property editor? Currently have this html:

<umb-property property="vm.name">
    <umb-property-editor model="vm.name"></umb-property-editor>
</umb-property>

And this JS:

vm.name = {
    alias: "name",
    label: "Name",
    value: "",
    view: "textbox",
    validation: {
        mandatory: true,
        mandatoryMessage: "A name is required"
    }
};

But I also want to check for other invalid contents.
