When tag appears in meta, it adds tag_ as prefix to other meta attributes.

[jonathanbranam]

This occurs with the frequently used meta.lastUpdated field. If this is changed, it will break any code that currently uses the name meta_tag_lastUpated.*.

E.g.

generic_codeable_to_dict({
    'tag': [
        {
                "system": "http://lifeomic.com/fhir/group",
                "code": "group-code-id",
            },        
    ],
    'other': 'ok',
})
>>> 
{'tag_other': 'ok',
 'tag_system__lifeomic.com/fhir/group__code': 'group-code-id'}
