Metadata does not determine data. If I write "created: 1810" on the
Haskell Report, that does not make it 200 years old. If I seve a JPEG
image as text/html, it's still a JPEG image. We just wouldn't expect a
browser to render it correctly, because the metadata is wrong.
Appendix C describes a subset of XHTML, such that a document in
conformance with it may be interpreted usefully as HTML by most web
browsers. The document is still XHTML, and may be given to XHTML or
generic XML tools without difficulty.

HTML and XHTML are not encodings of anything. They are markup
languages defined using SGML and the XML subset of SGML. There are
multiple HTML definitions of varying popularity, and the fact that we
can pass some XHTML documents to a web browser expecting HTML and get
acceptable results is consistent with the fact that we can pass HTML
3.0 (never implemented by any popular browser) with minimal loss.
