[R&D] Explore transforming an XLSForm into a Questionnaire for rendering in a UI (web, flutter, native android, etc) and saving FHIR resources on submission.

[fredhersch]

XLSForms drive a number of existing CHW applications in the ecosystem (Dimagi's Commcare, SurveyCTO, ODK, ONA, KoBoToolbox, etc). If we're able to support an XLSForm as input and render a native, flutter, web, etc interface and define a way to save FHIR resources from the XLSForm specification - there would be many people who could work with the FHIR SDK with their existing workflows/forms and FHIR resources would be instantly available.

We should also consider the case where a FHIR questionnaire could be turned into an XLSForm or XForm and produce FHIR resource records as a result.

This link may be useful for seeing how Enketo used XSLT to transform XForms into web forms: https://enketo.org/develop/

The idea is that same XSLT can turn FHIR resources into XForms and back (Questionnaires <> XForm)
