As it's an example, you probably want it to be unformatted - that is, you want the example in the final document to look the same as you wrote it, including line breaks and indentation.

The simplest way to archieve this is by indenting the entire example - one space will be enough. In POD, an indented paragraph is left as is - no formatting, and no processing for tags is done.

This will solve your problem.

Otherwise, if you do want things to be formatted, replace the < following the capital letter by E<lt>.
