Description

With #21899 and #21913 we introduced a wrapped xml feature/fix regarding wrapped elements in golang.
However we did a small mistake with the spec. You don't define the name of the element beside wrapped, that is the name of the list. The element must be named with xml at the element by itself.

wrong:

        photoUrls:
          items:
            type: string
          type: array
          xml:
            name: photoUrl
            wrapped: true

right:

        photoUrls:
          items:
            type: string
            xml:
              name: photoUrl
          type: array
          xml:
            wrapped: true

Suggest a fix

Start with the spec in the repository referenced by #21913 and reproduce the wrapped XML case in Swagger Editor. Compare the incorrect and corrected OpenAPI declarations, then run the relevant generation or validation checks for the Go output. Done means the item name is defined on the element and the wrapper produces the expected XML.
