[acceptance] ID parametre doesn't have any effect

As per the documentation, when I include the ID in the following tag doesn’t appear in the resulting HTML code:

[acceptance accept-this id:agree]

“accept-this” appears as the NAME but the ID is nowhere to be found.

I need the ID in order to make WCAG 2.0 level AA compliant accessible forms.

I am using the latest version of the Contact Form 7 plugins from wordpress.org.

Any assistance in resolving this issue would be most appreciated.

Best regards,

Michael
