Cisco AnyConnect Essentials + Embedded CA

[jagexsysadmin]

I have a Cisco ASA 5500 Series appliance.

I'd like to use the Embedded CA
There’s no documentation which states an AnyConnect Essentials license will suffice, over an AnyConnect Premium.
http://www.cisco.com/en/US/prod/collateral/vpndevc/ps6032/ps6094/ps6120/data_sheet_c78-527494.html hints at Essentials being enough, as it specifically mentions some features require Premium, but I really need to be sure.

Anyone out that using AnyConnect Essentials (so, anyconnect essentials: Enabled) AND the Embedded CA?

Thanks,
Dean

So, called Cisco end user support - they don't know the answer.

Surely someone has used this combination of features on an ASA ?

Any help much appreciated - the licenses are apparently non-refundable once applied, so I need to make the right choice.

Thanks,
