Create vm from template with custom name within vApp

I tried to create vm from template with custom name in vApp using RecomposeVAppParams command and used SourcedItem and CreateItem but I can't.
Every time I get "Bad request ... " error.

What is the correct way to do it?

<RecomposeVAppParams xmlns="http://www.vmware.com/vcloud/v1.5" xmlns:vcloud="http://www.vmware.com/vcloud/v1.5" xmlns:ns12="http://www.vmware.com/vcloud/v1.5"
