Topic: Inline CQL embedded in Questionnaire

I am trying to understand the concept and processing of inline CQL.
E.g. I have a questionnaire and would like to embed a CQL statement like so:
{
"linkId": "8",
"extension": [
{
"url": "http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaire-initialExpression",
"valueExpression": {
"language": "text/cql",
"expression": "Today() + 14"
}
}
],
"type": "date",
"text": "Form expiration date"
}
Is this the correct format in the "expression" element? Do I need to provide the FHIR version, context, etc? Is that possible to pass any parameters to the inline CQL? Would appreciate any pointers to some examples and the specs.

In SDC, there is discussion about this here: https://build.fhir.org/ig/HL7/sdc/behavior.html#calculations. There is also discussion about using expressions in general here, specifically the Evaluation Context discussion: https://hl7.org/fhir/clinicalreasoning-topics-using-expressions.html#evaluation-context
