composeVApp w/ 1 blank VM (ie not from another vApp or vAppTemplate)

Hi,

I can't figure out how to reproduce the following vCD UI use case:

Build New vApp

New Virtual Machine (full name, os settings, etc.).

Attach to a network.

I tried using ComposeVAppParamsType w/ InstantiationParamsType and SectionType.

I can't find any sample reproducing this use case. All samples refer to vApp creation w/ existing VMs.

Thanks in advance.
