Title: Bug/subscriptionId

### Description
An empty subscriptionId prior to this PR get the default value of 'No Subscription ID'.
The XSD doesn't allow this string for a subscriptionId and it needed to be fixed.
This PR is a preparation to the subsequent work of moving all expected rendered payload from the unit test functions to external files to be tested for XSD compliance.
