mozilla-central seems to ignore the EncodingDecl

<?xml version="1.0" encoding="utf-8"?>

Comment 5

[Masatoshi Kimura [:emk]]

HTML5 parser is supposed to ignore the XML-like encoding declaration. It is consistent with the behavior of Internet Explorer.

Comment 6

[Stefan]

The wording in the standard is not precise. (the testcase IS an XML document since it is successfully parsed with any conforming XML parser. It is only served with a non-approrpiate MIME-type of "text/html"). According to the (non-normative) phrase

| Note: For XML documents, the algorithm user agents must use to determine the
| character encoding is given by the XML specification. This section does not
| apply to XML documents. [XML]

in sec. 8.2.2 this section would NOT apply to the testcase.
