Adding a HyperLink to apex:messages on VF page

Question

Is there any way embed a link in an apex:Messages error message?
Below is the apex:Mesages compnent on my VF page. I cannot use apex:PageMessages because it does not support the style resources that I am using.

<apex:Messages styleclass="alert alert-error errorStyling" />

The most common solution I am seeing is to set the escape attribute to "false" under PageMessages, but this attribute is not supported in apex:Messages, only PageMessages.

Is there any way to add a link to Page:Messages like the link below?

String err = 'Testing For Message Link: <a href="http://www.google.com">Google or Something</a>.';
        ApexPages.addMessage(New ApexPages.Message(ApexPages.severity.Error, err));

          PageReference pageRef = ApexPages.currentPage();  
              return pageRef;  

Best,
CP

Use escape="false" and you need to use apex:pageMessages for escape

String err = 'Testing For Message Link: <a href="http://www.google.com">Google or Something</a>.';

In Page

<apex:pageMessages styleclass="alert alert-error errorStyling" escape="false"/>

Updates

If you can't use apex:pageMessages then use apex:outputText with escapse='false'

You can display this outputText when this string having value

<apex:outputText styleclass="alert alert-error errorStyling" escape="false" 
     value="{!errorString}" rendered = "{!(errorString != '')}" />

In Controller

public string str {get; private set;}

 str = 'Testing For Message Link: <a href="http://www.google.com">Google or Something</a>.';

IN VF page

<apex:outputText escape="false" value="{!str}"></apex:outputText>

NOTE:- As @Mohith Shrivastava said If you are building an appexchange product ,this wont pass security review .escape=false is not an option from security review perspective
