title: Add html tags to Struts 1.3.10 sources
body: <p>Hello StackOverflow community,</p>
  
  <p>I'm stuck with Struts 1.3.10 (no, I can't try migration to a better framework since my project was given to my team with 70% completion). I'd like to add HTML tags to the Struts taglib.</p>
  
  <p>I already know that for some tags (like <em>placeholder</em>) you can use jQuery but I'm not interested in that. <strong>I want to modify Struts sources</strong>. I've been looking for on the internet but nothing showed up that can help me. Maybe you can give me a hand with these matter.</p>
  
  <p>Examples of what I want to do:</p>
  
  <pre><code>&lt;html:text property="someProperty" placeholder="Hi..." length="30"&gt;
  </code></pre>
  
  <p>or</p>
  
  <pre><code>&lt;html:checkbox property="choice" data-on-color="primary" data-off-color="info"&gt;
  </code></pre>
  
  <p>or add any HTML property I want.</p>
  
  <p>Thanks in advance, I hope you can guide me.</p>
