How can I add validation to an Input field?
<p>Just learning SAP UI5, I have a simple input field like so:</p>

<p><strong>app.xml</strong></p>

<pre><code>&lt;Input
    placeholder="Please enter 10 digit number"
    value=""
/Input&gt;
</code></pre>

<p>I'm trying to understand how I can add a validation on the input field that does the following:</p>

<p>-Accepts a number of 10 digits or more</p>

<p>So far, what I understand, this can be setup in the following way:</p>

<pre><code>&lt;Input value=”{

    path : ‘/userName’,
    type : ‘sap.ui.model.type.Integer’,
    constraints : {
        minLength : 10
    }
}
</code></pre>

<p>Where I'm getting confused:</p>

<p>The input field is meant to act as a search bar, therefore I don't need to introduce databinding (search bar should not have an initial value) where I have to configure a path. Can someone explain to me how I can add validation without setting a 'Path'?</p>
