How do we envision querying QIR profiles and output schemas?

[echavarria-mqv]

The QIR specification suggests using 1) profiles (e.g., base and adaptive profiles) to list specific features of a target device (e.g., mid-circuit measurements) and 2) output schemas to determine how the results will be formatted when sent back to the middle-end (e.g., histograms). Although these concepts are well covered by the QDMI_query_device_property_XXX routines, I see two possible scenarios:

1. The MQSS asks the device if it recognizes the concepts of profiles and output schemas using QDMI_query_device_property_exists, and if it does, it uses QDMI_query_device_property_c for each specific query. What should be done if the answer is no?

2. The MQSS ignores the concepts of profiles and output schemas altogether and directly uses the QDMI_query_device_property_XXX routines for each query.

How should we tackle this issue, considering we are advocating for the QIR specification?
