Javascript 'cvml' in an email address

Question

I received a reply from someone with a Gmail address recently.

In the body of the message, it had my return address as:

"My name" <[email protected]<javascript:_e({}, 'cvml','[email protected]');>>

A search online shows this bit of JavaScript code appearing frequently in email messages but no explanation of what it does.

Is this something having to do with Google+?

What is its purpose?

Answer 1

I believe this stems from Cufon-yui.js, which is used to render custom fonts. Cufon uses cvml to return urn:schemas-microsoft-com:vml which is an XML namespace for Vector Markup Language.
