how to combine DCQL text language with ISO 18013-5 age_over_xx language

It's not very clear how DCQL is combined with ISO 18013-5's language - in particular:

https://openid.github.io/OpenID4VP/openid-4-verifiable-presentations-1_1-wg-draft.html#section-7.2.1

Select the data element referenced by the second component. If the data element does not exist in the Credential then abort processing and return an error.

and:

age_over_xx where ISO 18130-5 defines that if you, say, request age_over_18 and the credential only has age_over_19 then age_over_19 must be returned.

I'm not sure how it's best to fix this, but I presume the intention was that the ISO behaviour should be preserved, so a statement like this might be helpful:

Credential formats may define specific rules on selection of claims, for example age_over_xx in ISO mDL, that mean selecting the data element may not be an exact string match.
