Permit closing tag for new, void elements - for legacy compatibility = XHTML alignment

State:

CLOSED

Product:

pre-LC1 HTML 5 spec

Raised by:

Julian Reschke

Opened on:

2011-01-19

Description:

(raised on behalf of Leif Halvard Silli, see <http://www.w3.org/Bugs/Public/show_bug.cgi?id=8038>):


It is hereby suggested

* to permit a close tag for new void elements
* to require that the close tag of such elements would have to
immediately follow the open tag
meaning that a close tag separated by content would have to
be treated as just a stray close tag and a parse error.
Otherwise, if content were permitted and the HTML5-parsers were
required to look for the close tag that didn immediately follow,
then a an open tag alone wouldn't work , since the parser then
would have to parse to the end of the document
to know if there is a close tag.

This proposal is motivated by two factors: FIRSTLY, to be compatible with
HTML-parsers that haven't been updated to support a new void, element (and
thereby ease the introduction of new, void, elements) and SECONDLY, by a wish
to align the HTML syntax as much as possible with the XML syntax.
