Idiomatic way of dealing with unknown fields? [golang]

[joshchangNIH]

When parsing the CMS DPC synthetic test files ExplanationOfBenefit and Coverage do not parse cleanly.

err: error at "Coverage": unknown field

error at "ExplanationOfBenefit.extension[0].valueMoney": unknown field
error at "ExplanationOfBenefit.item[0].adjudication[0].amount": unknown field

How are y'all dealing with this? Thanks

Are the test files publicly accessible? Do you have a link?

From here: https://dpc.cms.gov/data.html

Patient parses fine

It looks like the test files you supplied are STU3 files. The errors you're getting are from trying to parse the resources as R4 resources (Patient has minor (maybe no) changes between versions)
