1.2.1. Documents
A document is a conforming HTML document if:
- It is a conforming SGML document, and it conforms to the
HTML DTD (see 9.1, "HTML DTD").
NOTE - There are a number of syntactic idioms that
are not supported or are supported inconsistently in
some historical user agent implementations. These
idioms are identified in notes like this throughout
this specification.
- It conforms to the application conventions in this
specification. For example, the value of the HREF attribute
of the <A> element must conform to the URI syntax.
- Its document character set includes [ISO-8859-1] and
agrees with [ISO-10646]; that is, each code position listed
in 13, "The HTML Coded Character Set" is included, and each
code position in the document character set is mapped to the
same character as [ISO-10646] designates for that code
position.
NOTE - The document character set is somewhat
independent of the character encoding scheme used to
represent a document. For example, the `ISO-2022-JP'
character encoding scheme can be used for HTML
documents, since its repertoire is a subset of the
[ISO-10646] repertoire. The critical distinction is
that numeric character references agree with
[ISO-10646] regardless of how the document is
encoded.
