State Manager doesn't support running associations that use a new version of a document if that document is
shared from another account. State Manager always runs the <code>default</code> version of a document if shared
from another account, even though the Systems Manager console shows that a new version was processed. If you want
to run an association using a new version of a document shared form another account, you must set the document
version to <code>default</code>.
