As code duplication increments the chances of bugs, security issues, code desynchronization issues (when you update in one place but not in the others), etc.

And these models are all sharing a lot of the data and duplicating attribute names and types.

We could do better.

    @Test
    public void test_render_xss_onclickAttribute() {
        String malicious = "<a href=\"#\" onclick=\"alert('XSS')\">Click</a>";
        String result = markdownRenderer.render(malicious);
        // onclick attribute should be removed
        assertFalse(result.contains("onclick"));
    }

    @Test
    public void test_render_xss_javascriptProtocol() {
        String malicious = "[Click me](javascript:alert('XSS'))";
