Status: RESOLVED INVALID

(Core :: CSS Parsing and Computation, defect)

Description

[testit]

Attachment: hyphenation_lang.html

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:8.0) Gecko/20100101 Firefox/8.0
Build ID: 20111104165243

Steps to reproduce:

I used moz-hyphens in a html and in a xhtml file and set the language attribute to "en".


Actual results:

It seems to be that different rules are applied, as the result looks different.


Expected results:

In both cases the same hyphenation rules should be applied.

If you serve your "XHTML" document as HTML it's treated as HTML.
  xml:lang="en"
is ignored in HTML parsing. So I think this bug is invalid.

What do you mean by "If you serve your "XHTML" document as HTML"?

serve it as text/html (rather than application/xhtml+xml)

In text/html, xml:lang is not honored; when lang is used the behavior is the same.  So I agree this is invalid.

Quoting  http://www.webkit.org/blog/68/understanding-html-xml-and-xhtml/ :

  In particular, none of the following things will cause your document
  to be treated as XHTML:
   - Using an XHTML doctype declaration
   - Putting an XML declaration at the top
   - Using XHTML-specific syntax like self-closing tags
   - Validating it as XHTML
