Describe the bug you're encountering

When providing examples via examples or example keyword for responses it will not be rendered according to media-type.

To reproduce...

Open yaml at editor and try to view xml response sample. You can delete the examples part and it will render it in xml.

Expected behavior

Examples provided via examples definition should be rendered respecting the content-type.
