Variations
RFC 1866 recommends that a document use the
header elements in order, without breaks, beginning with H1.
(ed: I have not identified a browser that enforces this.)
The LANG and DIR attributes are introduced with the
internationalization proposal.
The internationalization proposal also includes
ALIGN=center|left|right|justify
Netscape 2.0 implements
ALIGN=center|left|right
The ID attribute was proposed in HTML+ and Version 3
to replace the NAME attribute
in the A element to establish internal hyperlink destinations.
With the expected use of ID for style sheets, this is likely to change.
All other attributes are proposed in Version 3.
RFC 1866 states typical rendering is bold, normal font, indented more than H3.
Headings are Level 0 elements.
