question: how to have uuid.UUID as type but still specify `format: uuid` in openapi spec?

We have this UUID field:

```go
dsl.Field(0, "id", dsl.String, func() {
// Serialize it with `uuid.UUID`.
dsl.Meta("struct:field:type", "uuid.UUID", "github.com/google/uuid")

// Some other stuff, for tags in GO...
dsl.Meta("struct:tag:yaml", "id")
})
```
instead of

```go
dsl.Field(0, "id", dsl.String, func() {
// Use the string formatting checks.
dsl.Format(dsl.FormatUUID)

// Some other stuff, for tags in GO...
dsl.Meta("struct:tag:yaml", "id")
})
```

The latter however nicely puts the **`format: uuid`** on the openapi spec.

Is there a way to hack that in as well for the first use case which is much more nice to use in Go?
