How to store "<" in an XML attribute for configuration section?>

I'm using a custom configuration section in my web.config file for ASP.NET

One of my fields is: &l开发者_JAVA百科t;add percent="5" label="<5%" />

As you can see in label I have a "<" sign - this is causing errors. How can I store this value there without having compile issue?

Thanks!

The escape sequence for this character in XML is

<

The lt stands for "less than"
