Dynamic XFA forms and Acrobat Professional

Hi,

I have the following statement from our software vendor and want to check whether it's correct: "You cannot create/edit dynamic XFA forms using Adobe Acrobat. Creating dynamic XFA forms requires Adobe LiveCycle Forms Designer that shipped with Acrobat 7, 8, 9 and X Professional; and, is not included with Acrobat XI Professional. You can populate forms using Acrobat Professional but these are static forms."

Is this correct? Between the change in the way LiveCycle designer has been distributed (packaged with Acrobat Pro then separately) and Acrobat Pro vs Adobe FormsCentral, it's not easy to see what is needed to do what now with Acrobat Pro XI.

Thanks!

R.
