Appendix C is a set of guidelines to make XHTML documents (sort-of)
compatible with HTML user agents.  Those are NOT guidelines to make
HTML documents compatible with XHTML.  XHTML 1.0 is a reformulation
of HTML 4 in XML 1.0 but XHTML 1.0 and HTML 4 are not fully
compatible, due to differences between SGML rules used for HTML (as
elaborated in the SGML declaration for HTML 4) and XML's.
