multiple templates are referenceable as input for a response

[teb510]

in the below example - i create two templates and then use them both as inputs for the response. only the first template is used (confirmed this by swapping them around). i feel something should be explicit here - you cannot set multiple templates as inputs for the response. i think this should return an error.

Agreed, we're not validating on the numbers of inputs/outputs based on node type. Ideally, this should be done at the schema validation level, but I'm not sure if JSON Schema is smart enough for this. If it isn't, we'll have to validate at runtime.
