How can this be made to pass W3C's standards and validate correctly?

I cannot change the document type definition and the non-standard attributes are required.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Demo</title>
</head>

data-* is an HTML5 custom attribute, it is not valid in any other versions of HTML/XHTML as you are using so just change your doctype to
<!DOCTYPE html>

You've kind of answered your own question:

How can this pass standards when using non-standard attributes!

Simple answer is - it can't. If you need non-standard attributes, then accept that it will fail standards validation

Don't understand why you cannot change the doctype.
