Structure requirements for parametrized attribute

Fields

args: HashMap<String, ValueReq<ArgValue>>

Specifies all named arguments and which requirements they must meet

paths: ListReq<Path>

Specifies whether path arguments are allowed and with which requirements.

integers: ListReq<LitInt>

Whether integer literals are allowed as an attribute argument and, if yes, with which requirements

literal: (LitReq, ValueReq<Lit>)

Which other literals are allowed and which requirements should apply.

NB: Non-string and non-integer literals may be always present only once.
