Did you read the spec?

If you've got something in your .xml file like this

    <userProperties>
        <property type="string" name="user" minLength="0" maxLength="32" label="Username" />
        <property type="password" name="pass" minLength="0" maxLength="32" label="Password" />
    </userProperties>

In your .js file, you can set them with this:

this.createPropertyEditor();

and refer to them:

this.getUserProperty("user");
this.getUserProperty("pass");
