New Post: Clarification on the new Provision synax

I am just migrating an old 3.93 based script to the latest 3.96 standard and to add to the complications from SP2010 to SP2013

The new provision syntax used to require either "true" or "false"; whereas, the new syntax means can specify the SharePoint server we want provision the service app on (see code below) . So is the following valid settings for provision

"localhost" - the current server
"true" - similar to localhost so current server
"false" - don't provision anywhere
"servername" - provision the service on the named server.

<ManagedMetadataServiceApp Provision="localhost"
                                   Name="Managed Metadata Service"
                                   ProxyName="Managed Metadata Service">

cheers
Daniel
