Is VC compatibility with older versions of Dragon?

I have received a request from a Legal Professional in the UK who is interested in VoiceComputer. He is <span style=“font-size:10.0pt;font-family:“Lucida Sans Unicode”,sans-serif; mso-fareast-font-family:Calibri;mso-fareast-theme-font:minor-latin;mso-ansi-: EN-GB;mso-fareast-:EN-US;mso-bidi-:AR-SA”>particularly
interested in the ‘intags’ facility. However, this person is running Dragon NaturallySpeaking Professional 11.

Is the latest version of VoiceComputer (14) compatible with Dragon Professional 11?

Thank you.
