`type="text/html, application/xml"`
I don't think so. [RFC 8288 ยง3.4.1](https://tools.ietf.org/html/rfc8288#section-3.4.1) says
> The "type" attribute, when present, is a hint indicating what the media type of the result of dereferencing the link should be. Note that this is only a hint; for example, it does not override the Content-Type header field of a HTTP response obtained by actually following the link. The type attribute MUST NOT appear more than once in a given link-value; occurrences after the first MUST be ignored by parsers.
The ABNF for the type parameter's value is:
type-name "/" subtype-name ; see Section 4.2 of [RFC6838]
So it does not seem that `type="text/html, application/xml"` is valid.
